- Communicator
4.5 Release Notes
These release
notes, last updated October 19th, describe installation issues
and known problems in Communicator 4.5. For an overview of the
new features provided by Communicator 4.5, see the Tour of New
Features.
These notes are
updated as we receive feedback, so please check back for new
information.
Before
You Install
- Note that
Communicator 4.5 does not run on Windows 3.1 or on
Macintosh 68K systems. Communicator 4.07 does run on both
of these operating systems, and systems running
Communicator 4.5 are fully compatible with those running
the 4.07 and earlier versions.
- On Mac OS
and Windows systems with an existing version of
Communicator: If you use SmartUpdate to upgrade to 4.5,
be sure to click the Grant button when the Permissions
dialog box appears during the installation. Clicking
Grant enables the installer to continue, and you can
still cancel the installation later in the process. If
you click Deny, a series of Permissions dialog boxes
appear, and the system sometimes quits with an error -1.
- On Windows
and Mac OS systems: If you used Communicator 4.5 PR2 to
set passwords for your profiles, be sure to clear those
passwords before you install this final version of
Communicator 4.5, otherwise you won't be able to change
the passwords in these profiles. To clear your passwords,
run the User Profile Manager, which appears in the
Windows Start menu (Communicator, Utilities) and in the
Mac OS Communicator folder. Select the appropriate
profile, then choose Change Password and leave the new
password fields blank. System administrators can use
Mission Control Desktop to enable the profile password
feature in the netscape.cfg file.
- If you are
upgrading from Navigator 2.0 or 3.0, you need to
re-install any plug-ins that you want to transfer to
Communicator 4.5. In order for Communicator to
automatically transfer plug-ins from 4.0x versions, you
must install Communicator 4.5 in the same folder as the
old 4.0x version. If you install 4.5 in a different
folder, you must re-install any plug-ins.
- On Mac OS
systems: If you are using a 3.0x version of Navigator and
want to transfer your preferences automatically to
Communicator 4.5, first upgrade to Communicator 4.07,
then install Communicator 4.5.
- On Mac OS
systems: Mac OS 7.6.1 or greater is required to run
Communicator 4.5. For current Apple Mac OS software, see http://support.info.apple.com. These are the
recommended minimum system hardware configurations:
- Mac
OS 7.6.1: 16MB physical RAM
- Mac
OS 8.0 or greater: 24MB physical RAM
- On Mac OS
systems: Before you install Communicator, make sure that
your hard disk names do not include the slash (/)
character. Account Setup won't run if any of your hard
disk names include the slash (/) character.
General
Issues
- On Mac OS
and Windows systems: New profiles created in Communicator
4.5 aren't recognized by previous versions of
Communicator or Navigator.
- If you
change your user name on an IMAP server, you need to
restart Communicator for the name change to take effect.
- In Calendar
on Mac OS and Windows systems: If you enter an invalid
server name Calendar sometimes appears to
"hang," in which case you need to restart
Communicator.
- Exported
certificate names are appended with either letters or
numbers. Communicator doesn't check for duplicate names,
so make sure to use a unique name for each certificate.
- Composer
doesn't properly handle existing HTML files that contain
CSS objects -- they may be removed from the file.
Roaming
Access
- On Windows
systems: Clicking Cancel while uploading or downloading
to an HTTP Roaming Access Server sometimes causes
Communicator to quit.
- When using a
slow connection, be patient with the progress dialog
boxes. Sometimes they don't immediately respond to your
input during file transfers.
- If you
choose not to transfer your preferences, Communicator
does not transfer your address book and IMAP mail
filters, which are stored with preferences.
- On Mac OS
systems: If you enable Roaming Access, Communicator
doesn't save subscribed newsgroups. To save subscribed
newsgroups, go to the Edit menu and choose Preferences.
Under Roaming Access, select Item, and remove the check
from the Mail Filters box in the right frame.
Mail,
Address Books, and Pinpoint Addressing
- If you are
upgrading from Navigator 3.0x, you need to manually
import your 3.0x address book into Communicator 4.5 by
opening the address book window and choosing Import under
the File menu. On Mac and Windows, then select
Communicator Address Book at the prompt. Enter the name
of your 3.0x html address book file.
- On Windows
and UNIX systems: Removing ns_imap folders causes
Communicator to lose the mail filters you have set up. If
you suspect corrupted mail summary files, be sure to just
remove the files, not entire folders or directories.
- Communicator
4.5 allows you to create multiple address books. Pinpoint
addressing searches the first 15 address books in your
address book window. If you have more than 15 address
books, you can select the 15 you want to use by
re-ordering them in the address book window.
- Pinpoint
addressing in Communicator 4.5 searches for matches
against the display name, last name, email address and
nickname. Communicator 4.0x gave precedence to nickname
matches. If you want exact matches against a nick name to
have precedence over matches against the other fields,
add this line to your javascript preferences file:
user_pref("ldap_2.autoComplete.nicknameHasPrecedence",
true);
- If you have
an LDIF file representing an address book that was
generated from Communicator 4.0x and contains 8-bit data,
you can correctly import the 8-bit data into Communicator
4.5 by changing the file extension of your LDIF file to
.4ld. Then, import the LDIF file like you normally would,
using this new extension. You only need to do this if the
file with 8-bit data was generated from a previous
version of Communicator.
Navigator
- Some HTTP
proxy servers don't support Internet Keywords when the
user supplies only one keyword, instead giving the error
Could Not Find Host.
- When a page
is refreshed by the Reload button or a meta tag, the
actual last-modified field of an image is not being
compared. Sites such as those with webcams can force a
refresh by adding:
<META HTTP-EQUIV="Pragma"
CONTENT="no-cache">
<META HTTP-EQUIV="Refresh"
CONTENT="60">
- By default,
when saving from an FTP server in Navigator, Communicator
saves binary files as HTML files.
International
- Previous
Windows versions of Communicator had a problem sending
the Accept-Language HTTP header to servers. This problem
occurred if you used the Preferences command to add
choices to the default language selection. This problem
is corrected with Communicator 4.5. If you create a new
profile to use in the 4.5 release, you don't need to do
anything else to remedy the problem.
If you are
using a profile created in a previous version of
Communicator, you need to overwrite the old preference
settings with the correct ones. To correct the preference
settings, from the Edit menu, choose Preferences. Under
the Navigator category, select Languages. Either confirm
that all the selections in the right pane are correct, or
delete and re-enter them. Click OK.
- If you have
address books that you created using Communicator 4.5PR1
or 4.5PR2, you may wish to re-import them to ensure that
Communicator sorts correctly based on your system locale.
To re-import your address books, create a new address
book in the address book window. Select the new address
book, then open the File menu and choose Import. Enter
the file name of your address book, which you can look up
in your preferences file under the heading
ldap_2.servers.pab.filename.
Another way
to re-import your address book is to create a new address
book and then drag all of the entries from your old
address book to your new address book in the address book
window. Then delete your old address book.
- Windows
systems: Communicator quits on some Japanese web pages
that use an external style sheet definition file. To view
such pages, go to the View menu and select Character Set,
then Japanese (Auto-Detect). With this setting, the style
sheet definition does not load but you can view the
entire page. Another way to view these pages is to
disable style sheets: From the Edit menu, choose
Preferences. Select the Advanced category. In the right
pane, deselect "Enable style sheets."
- On some
Japanese web pages, Communicator doesn't load external
style sheet definitions if the Character Set command in
the View menu is set to anything other than Western.
- When using
the User Profile Manager to create a new profile, some
Japanese characters that you enter in the Profile Name
field of the "Choose a Name and Directory for Your
Profile" dialog don't appear correctly in the
directory. To correct the directory entry, delete the
directory name and manually type the correct Japanese
characters.
Windows
- If you
upgrade from Navigator 3.0 to Communicator 4.5, follow
these steps to preserve your existing bookmarks and
address book:
After you
launch Communicator 4.5 for the first time, when the
Upgrade Navigator Settings window appears, select
"Copy my existing user files to the new profile
directory." (If you select the default,
"Move my existing user files to the new profile
directory", your bookmarks and address book
sometimes doesn't transfer correctly. If you've already
upgraded and cannot access your bookmarks and address
book from Communicator 4.5, you can copy the files
bookmark.htm and address.htm from your Navigator
directory, usually c:\Program Files\Netscape\Navigator,
to your profile directory, usually c:\Program
Files\Netscape\Users\default.)
- Messenger
sometimes quits when new folders are subscribed to with
SSL. This problem apparently occurs only when you
automatically subscribe to all your folders on the
server. To avoid it, manually choose the folders to which
you wish to subscribe.
- If you are
downloading a large file and you click Cancel,
Communicator may quit.
- If you send
an email message and attach a web page that contains
frames, the recipient will receive the message, but with
a blank attachment.
Palm-Compatible
Synchronization Tools (Windows Only)
- Back-up your
Palm-compatible address book before using Address Book
synchronization.
- These are
issues to be aware of when you synchronize the Palm
address book with the Netscape Address Book:
- If
there are multiple lines in Palm fields (not
including address and notes) Communicator
converts those entries to a single line separated
by commas.
- Communicator
does not automatically synchronize Palm custom
fields. For more information on how to map fields
between Palm and the Netscape address book
fields, see the Palm Synchronization Read Me.
- To
synchronize with a directory that is synchronized
offline, set Communicator to Offline.
- To
work with mail synchronization, we recommend that
you send mail from Palm.
Mac
OS
- To optimize
plug-in loading time, move any Read Me files that may be
installed in the plug-ins folder to another folder on
your hard disk.
- When
uploading a file using ftp, Communicator only sends the
data fork of the file. If you want to upload a Macintosh
file that has a resource fork, convert the file to BinHex
or MacBinary first.
- Folders
aliases are not supported. You can drag a folder to an
ftp directory window for upload but only aliases to files
are resolved before they are uploaded.
- When
dragging a folder to upload, the directory hierarchy of
the folder is not maintained. All files contained in the
dragged folder, even those in sub-folders, are uploaded
to the directory you are logged into.
- Older
versions of Norton CrashGuard are incompatible with
Communicator 4.5 and may cause your system may
"hang" or "quit."
- If you are
using Mac OS 8.1: You may have problems with some text
files if you start Communicator using Easy Open. To avoid
these problems, when the Easy Open dialog appears, do not
make a selection, and cancel the dialog box. Open
the MacOS Easy Open control panel. Uncheck the
option "Translate 'TEXT' documents".
Close the Control Panel. You can then select your
signature file.
- If you see
errors or problems while running a plug-in, quit
Communicator. Then click the Netscape Communicator icon
on the desktop. From the File menu, choose Get Info, then
increase the number in the Preferred Size field by 1024.
- If you use
the Real Player 5.0 Player and its plug-in software that
comes with Communicator 4.5, be sure to keep the
Communicator memory setting at or above the default
preferred size: 8192K with virtual memory turned on.
Reducing this memory setting may cause your system to
quit when you use Real Player. For more information, see
the Real Player site and documentation regarding
recommended memory requirements.
- If you have
Adobe Type Manager installed, Communicator sometimes
quits after you use the Font Preferences panel or pop-up
menus on some systems.
- Versions of
Speed Doubler up to and including 1.0.1 are incompatible
with Navigator and Communicator. Some disk cache
operations may cause b-tree corruption on your hard
drive. To correct this problem, download the latest
version of Speed Doubler from the Connectix site:
http://www.connectix.com
Java
and JavaScript
- JavaScript
1.3 contains an ECMA-compliant fix regarding assignments
such that if (a=b) is no longer interpreted as if (a==b).
You can update the code or, if you want the old behavior,
specify <SCRIPT
language="JavaScript1.2">.
- If you use
an applet that uses RMI callbacks, you must call
netscape.security.PrivilegeManager.enablePrivilege("UniversalConnect")
before your first call into the RMI runtime.
Unix
- The Linux
2.0 version of Communicator is linked against libc
5.4.22, libm 5.0.8, and XFree86 3.2.
- The Linux
2.0 glibc version of Communicator is linked against glibc
2.0.7 and XFree86 3.3.1
- If this is
the very first time you've run any version of
Communicator on your system, start Communicator, then
exit, then start Communicator again before you use
Messenger to access your mail. If you attempt to use
Messenger the very first time you run Communicator, it
may quit with an "Illegal instruction" message.
- If you are
using IMAP mail and would like your Sent, Templates, or
Drafts folders to be located on your IMAP server, first
create the folder on the server, then use Communicator
Preferences to specify that you want Sent, Templates, or
Drafts folders to be kept on the IMAP server.
- To copy
messages from one IMAP server to another, use the File
toolbar button. You cannot drag and drop of messages from
one IMAP server to another.
- If you
delete your only IMAP server and then add a POP server,
Communicator may quit.
- If you
receive Motif warnings that appear as dialog boxes, you
can send those warnings to the command line instead by
adding these lines to the file ~/.Xresources:
Netscape*useStdoutDialog:
False
Netscape*useStderrDialog:
False
- You should
set the CLASSPATH environment variable only if you need
to install special Java files in Communicator.
Communicator uses CLASSPATH to find local .class
files. If CLASSPATH is set in the user's environment,
only the .jar files and directories specified in the
CLASSPATH are searched. If you set your CLASSPATH
variable, you need to make sure that each .jar file in
$MOZILLA_HOME/java/classes is listed individually in your
CLASSPATH.
- A previous
workaround for Unix systems, to avoid the freezing on
startup of the edit or compose window, has been changed.
If you previously set editor.disable_spell_checker in the
preferences.js file, you can now implement the improved
fix by deleting this line from the preferences.js file:
user_pref("editor.disable_spell_checker",
true); Replace it with this line:
user_pref("editor.dont_lock_spell_files",
true)
This
preference setting prevents the spell checker from
locking files over NFS, thereby preventing the window
freezing problem.
- AIX systems:
Some pages and windows may not display correctly the
first time you run Communicator. Restarting Communicator
corrects this problem.
Installing
Digital Unix
This section
applies if you are installing Communicator 4.5 on Digital UNIX
versions prior to 4.0D.
Communicator 4.5
was built against C++ shared libraries that you need to install
from this location:
ftp://ftp.digital.com/archive/private/netscape/CXXREDIST600V01.tar
If you don't
install the C++ shared libraries before installing Communicator
4.5, errors of this kind will appear during Communicator
installation:
- %
netscape
netscape: /sbin/loader: Error: unresolvable symbol in
netscape:
__cxx_exception_caught
netscape: /sbin/loader: Error: unresolvable symbol in
netscape:
__cxx_handler_exit__X4need3new8libcxxso
netscape: /sbin/loader: Error: unresolvable symbol in
netscape:
__cxx_v60_dispatch__X4need3new8libcxxso
netscape: /sbin/loader: Fatal Error: this executable has
unresolvable symbols
To install the
C++ shared libraries:
1. Check
which CXX subsets are installed:
-
setld -i | grep CXX |
grep installed
If either subset CXXLIB601 or
CXXREDIST601 is installed, there is no need to install
from CXXREDIST600V01.tar.
2. Untar
the file:
tar xvf
CXXREDIST600V01.tar
This
creates a setld kit for installing libcxx.so in directory
CXXREDIST600.kit.
3. Log in
as superuser.
4. Enter
this command
setenv LD_LIBRARY_PATH
${LD_LIBRARY_PATH}:/usr/lib/cmplrs/cxx
5.
Install by entering this command and selecting the subset
displayed:
/usr/sbin/setld -l
CXXREDIST600.kit
For DIGITAL UNIX
Version 4.0D and later, /usr/shlib/libcxx.so (installed by the
operating system) contains the support needed for DIGITAL C++
Version 6.1.
For DIGITAL UNIX
versions prior to V4.0D, the libcxx subset and the redistribution
subset both install /usr/lib/cmplrs/cxx/libcxx.so to avoid
overwriting the version of libcxx.so installed by the operating
system (/usr/shlib/libcxx.so). When linking, the compiler pass
-rpath /usr/lib/cmplrs/cxx -L/usr/lib/cmplrs/cxx to ld. This
causes ld to search /usr/lib/cmplrs/cxx before searching the
system libraries, and the loader to search for libraries in that
directory when loading code for execution. If you specify -rpath
explicitly, you need to make sure to specify /usr/lib/cmplrs/cxx
in the path string in addition to any other directories that you
want searched.
Using the
Quality Feedback Agent with Automatic Proxy Configuration
If you are using
automatic proxy configuration, and you want to use the Full
Circle Talkback Quality Feedback Agent to send incident reports
to Netscape, you need to replace the talkback.ini file with one
that contains the appropriate proxy configuration information:
1. If
you are using an HTTP proxy, or both an HTTP and SOCKS proxy,
create a file named talkback.ini, containing these
three lines, using your proxy host name, domain, and port:
UseUserHTTPProxyInfo=1
UserHTTPProxyHost="yourproxy.yourdomain.com"
UserHTTPProxyPort=xxxx
If you are using a SOCKS Proxy, create a file with these
three lines:
UseUserSOCKSInfo=1
UserSOCKSHost="yourproxy.yourdomain.com"
UserSOCKSPort=xxxx
- 2. Replace
the existing talkback.ini file with the version you
created.
On
Windows 95 and Windows NT systems, copy the talkback.ini
file to this location, in the directory containing
Netscape.exe:
\Fullsoft\data\talkback.ini
On Mac OS
systems, copy the talkback.ini file to this location in
the System Folder:
Preferences:Full
Circle:Prefs:Netscape:Communicator4.5:98xxx:Talkback.ini
On Unix
systems, copy the talkback.ini file in to this location:
$HOME/.fullcircle/Netscape/Communicator4.5/98xxx/Talkback.ini
