KNOWN ISSUES

General

  • On some Windows 95 systems, installing Communicator 4.02 causes the ODBC32 control panel to exit with an illegal operation. This may be related to an ODBC incompatibility with new system DLLs installed by Communicator. A workaround is to install a SmartUpdate package located at ftp://ftp.netscape.com/pub/communicator/smartupdate/msvc.jar.

Navigator

  • If you are running Netscape Communicator on Windows NT 3.51 using a Matrox Millennium graphics driver, an application error may occur when viewing HTML pages. Obtain an updated version of the driver (version 2.25 or later).
  • If a system halt related to the Kernel32.dll occurs, update the kernel. You can obtain the update from http://www.microsoft.com/kb/articles/q148/3/36.htm. This may correct the problem.
  • When browsing Web sites using Java content with your system's color depth set at 32-bit True Color, Navigator may stop responding. A simple workaround is to avoid using 32-bit color display.
  • If you uninstalled beta versions of Communicator (Preview Release 5 or earlier) on Windows NT systems, you may experience trouble running .avi, .wav, .mid, or .rmi files.

  • To fix the problem:
    1. Open the Control Panel and select one of the following:
      • For NT 3.51, select Drivers.
      • For NT 4.0, select Multimedia - Devices.
    2. Add the following drivers if they are not already listed: (MCI) CD Audio, (MCI) Microsoft Video for Windows,  (MCI) Midi Sequencer, and (MCI) Sound.
    3. Run regedt32.exe and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI Extensions.
    4. Select Add Value from the Edit menu; for Value Name enter avi, and for String enter avivideo.
    5. Select Add Value and for Value Name enter wav, and for String enter waveaudio.
    6. Select Add Value and for Value Name enter mid, and for String enter Sequencer.
    7. Select Add Value and for Value Name enter rmi, and for String enter Sequencer. You don't need to modify the data type.
  • In a frame document, only the activated frame is printed, because only one frame can be printed at a time. To activate a frame, click on it.
  • Printing documents with applets, plugins, and webfonts on layer do not work properly.
  • The paddings property of Style Sheets is not supported. Use topPadding, rightPadding, bottomPadding, and leftPadding instead.
  • The margins property of Style Sheets is not supported. Use leftMargin, rightMargin, and bottomMargin instead.
  • Width, height, and border tags for images in Style Sheets are not enabled.
  • Under certain circumstances in a table cell, the EMBED tag parameter ALIGN=RIGHT causes the plugin not to be loaded or displayed. As a workaround, insert the ALIGN=RIGHT parameter in the table column and/or row descriptors.

Composer

  • Starting Composer from the command line with netscape -edit (or double clicking on the Composer icon) does not start a new window if any other Communicator window is already active.

Messenger

  • If you encounter a general protection fault in msvcrt.dll when sending a message, exit Communicator.  This is caused by a .tmp file Windows limitation. See your system administrator or equivalent about removing these .tmp files from the Windows temp folder.  Afterwards, you can send messages from Communicator.
  • If a system halt occurs when invoking the Compose window, rename the address book file (abook.nab) located in the Program Files\Netscape\Users\<username> directory.
  • If you get an error regarding expired certificates when sending/receiving signed or encrypted mail, please go to http://www.verisign.com/update/faq/index.html to update your certificate.

Plug-ins

  • In 8-bit (256 color mode), you might experience color palette problems while loading some plug-ins in Communicator. As a workaround, try minimizing and then restoring the window or open a new Navigator window. Running in 16-bit (high color) mode will eliminate this problem.
  • Sound files greater than 6MB are not supported in the 16 bit version and may not play back properly.
  • Plug-ins installed in previous version of Navigator are not automatically transferred to Communicator. Re-install these plug-ins.

Netcaster

  • It is required that you use Communicator 4.02 with this version of Netcaster.
  • Java and JavaScript must be enabled to run Netcaster.
  • It is recommended that you select the Go Offline option from the File Menu before viewing sites offline.
  • The order of the channels in the selector may change after exiting Netcaster.
  • The Automatically Load Images preference (Preferences, Advanced from the Edit menu) should be checked.
  • A Netcaster icon in StartMenu/Programs/Netscape Communicator may remain from a previous installation. Please ignore or delete this icon.
  • If you specify an invalid URL when adding a channel, the channel is added under My Channels, but does not appear when you select it. A green light may also appear; ignore this light.
  • If you change a webtop to a channel in Channel Properties, the webtop remains on your screen. Close the webtop and when you select it again in My Channels, it appears as a channel in a Navigator window.
  • If you change your Communicator preferences, such as color or font, while Netcaster is open, a system halt may occur. Change your Communicator preferences before starting Netcaster.
  • The buttons in the Netcaster window may disappear depending on the font you select.
  • Select a channel before modifying any security information in the Options dialog.
  • Your channel settings may not be preserved if Communicator terminates abnormally.
  • If you change your screen's resolution while Netcaster is running, the Netcaster window may no longer be visible.
  • The display and cache size of the Castanet channels cannot be modified.
  • If you add a Castanet channel by specifying its IP address and then access the channel again by specifying its DNS name, Netcaster will attempt to resubscribe to the channel.
  • Before deleting an updating channel, click Stop Update.
  • When adding a channel, make sure to include a name and valid URL.
  • Unless you specifically use the Update Now command to update a channel, at most, two channels will update at the same time.
  • To remove files that were cached and reclaim the disk space they occupied, delete the channel. You can also use the Clear Cache command from the Properties dialog box.
  • Some of the channel preferences may not be visible until you restart Netcaster.
  • If you add two channels with the same name, an error may occur.
  • You cannot move a webtop, as indicated in the Netcaster NetHelp.

SmartUpdate

  • If a SmartUpdate download of an item occurs while the item to be updated is open or in use, restart your system for the update to take place.
  • On Windows 16-bit platforms, using the SoftwareUpdate GetWinProfile() and GetWinRegistry() methods may cause Communicator to halt. This has been fixed in Communicator 4.04.

Cosmo Player

  • On Windows 3.1, you may experience a system halt when exiting Cosmo Player.
  • During loading of Cosmo Player within Communicator 4.0, there is a direct draw initialization error with some older graphics display drivers on Windows NT 4.0. Click OK to continue.
