Netscape Communicator 4.61 for OS/2(R) Warp (Beta version) README This README contains the latest information about using this feature. Note: To help you locate information in this README, you can use the Find option under the Edit menu of the OS/2 System Editor. You can print the file by dragging it to your printer object or by selecting Print from the file object's pop-up menu. Using the right mouse button, click the object to display the pop-up menu. In the following sections, Netscape Communicator refers to Netscape Communicator 4.61 for OS/2 Warp. CONTENTS __________________________________________________________________ 1.0 Known Limitations 2.0 Problem Reporting and Survey 3.0 Notices 1.0 KNOWN LIMITATIONS __________________________________________________________________ The following limitations might occur or exist in Netscape Communicator. To view the latest information about known limitations for Netscape Communicator, click Release Notes from the Help menu. For information on how to report any limitations, click Product Information and Support from the Help menu. 1.1 General ------------------------------------------------------------------ o Netscape Communicator supports the IBM OS/2 Warp Developer Kit, Java(TM) Edition, version 1.1.7 and higher. If you have an earlier version of Java, upgrade to the latest version. You can download the latest version from the Software Choice Web site: http://service.boulder.ibm.com/asd-bin/doc/ o During installation, if a message is displayed stating that you do not have the correct FixPak level installed and you have verified that you have the correct software requirements (see the README.ICN file for installation and configuration information), then edit the NS46COMM.PKG file. Delete the following three lines: FILE EXITWHEN = 'INSTALL&& ("%NSWS%" == "FALSE")', EXIT = NETSCAPEFIXPAK o For monitors set to a resolution of 1024 x 768 or higher, the default font of Tms Rmn 10 pt. might cause overlapping. Change the default font to Tms Rmn 8 pt. to correct this problem. To change the font: 1. Click Edit --> Preferences --> Fonts to display the Fonts window. 2. To the right of Variable Width Printer Font, click Select. 3. In the Size box, type or select 8. 4. Click OK to close the Font window. 5. Click OK to save your changes and close Preferences window. o When using some font sizes, text on some Web pages might overlap or appear outside areas defined by the background color. To correct this problem, change the font. See above for instructions. o Drag and drop is supported only to the OS/2 Desktop and within Netscape Communicator. o The Print Preview function is not available. o When launching Netscape Communicator 4.61 from an icon while Netscape Communicator 4.04 is running, you may receive a network-related error message. This error message does not actually indicate a problem. If you click OK, you can continue to use the new Communicator window. 1.2 Security ------------------------------------------------------------------ Netscape Communicator uses the Netscape Security model, instead of the Java Security model used in Netscape Navigator 2.02 for OS/2. The following limitations occur as a result of this difference. o Netscape Communicator cannot load applets signed with the Netscape Signing Tool (SignTool) when these JAR files reside in the CLASSPATH. If you attempt to load one of these applets, the following error message appears on the Java console: java.io.IOException: bad zip file format JAR files signed with SignTool that are loaded through the URL or from a local hard drive directory that is not in the CLASSPATH can be successfully loaded. o Netscape Communicator can load applets signed with Sun's Javakey signing tool. However, if these applets use the Netscape security APIs (for example, enablePrivilege/revertPrivilege), the following error message appears on the JavaConsole when you attempt to load the applet: ForbiddenTargetException: User didn't grant the xxxxxxxx privilege. To resolve this problem, have the originator of the JAR file sign the JAR file using Netscape's SignTool. o Applets and JAR files requiring special privileges to system resources (for example, file system access or additional network access) must use the Netscape security model. o When signed applets are loaded from the network, the classes must be signed using the Netscape SignTool and you are prompted to grant permission. o When signed applets and JAR files are in the CLASSPATH, you are not prompted to grant permission. Permission is automatically granted whether the applet or JAR file is signed or unsigned. o If an applet needs to download files onto your local drive, you are prompted to grant permission. Be very careful when allowing an applet even limited access your file system even if it is a signed applet, unless you fully trust the signer. If you allow these files to be downloaded or otherwise placed in the Java CLASSPATH, these applets might gain full access to resources on the machine, including full access to your file system. o The UniversalMemberAccess privilege cannot be granted or enabled. 1.3 Performance ------------------------------------------------------------------ o The help might take a long time to display. Avoid opening more than one session of help for better performance. o If you don't specify an Initial Java Heap (IJH) size, Netscape Communicator lets Java set the default. Java does not take into account the size of Netscape Communicator when it calculates the default IJH size. The default is determined by how much memory the machine has. Java sets a default IJH size when Netscape Communicator runs an applet. The default memory is reserved by Java until Netscape Communicator is closed. Set the Initial Java Heap size as follows: 1. Click Edit --> Preferences --> OS/2 Preferences to display the OS/2 Preferences window. 2. Click IBM(R) Java Properties. 3. In the Java Options box, type -ms<number><m or k> where number depends on the following, and m stands for megabytes and k for kilobytes: - If you have 32MB or less of system memory, set the IJH size to 4MB (-ms4m). - If you have 64MB of system memory, set the IJH size to 8MB (-ms8m). - If you have 80MB or more of system memory, let the IJH size default. 1.4 DBCS Information ------------------------------------------------------------------ o If you are using the English version of Netscape Communicator on a Korean operating system, entering text with the NUM LOCK on can cause numbers to appear in the text. o For some DBCS Web pages to print correctly, you need to do the following: 1. Click Edit --> Preferences --> Fonts to display the Fonts window. 2. To the right of Variable Width Printer Font, click Select. 3. In the Name box, select o Japanese - OS/2 Warp 4: MINCHO/HeiseiMincho-P or other outline font. - All versions of OS/2 Warp Server: HeiseiMincho-W3-90-TT/Normal or other outline font. o Korean - OS/2 Warp 4: MINCHO/IBM Myung Jo or other outline font. - All versions of OS/2 Warp Server: Myung Jo or other outline font. o Traditional Chinese: - OS/2 Warp 4: System default or other outline font. - All versions of OS/2 Warp Server: System default or other outline font. o Simplified Chinese: - OS/2 Warp 4: Song Ti Chang Gui or other outline font. - All versions of OS/2 Warp Server: Song Ti Chang Gui or other outline font. 4. In the Size box, type or select 10. 5. Click OK to close the Font window. 6. To the right of Fixed Width Printer Font, click Select. 7. In the Name box, select o Japanese - OS/2 Warp 4: MINCHO/HeiseiMincho or other outline font. - All versions of OS/2 Warp Server: HeiseiMincho-W3-90-TT/Normal or other outline font. o Korean - OS/2 Warp 4: MINCHO/IBM Myung Jo or other outline font. - All versions of OS/2 Warp Server: Myung Jo or other outline font. o Traditional Chinese - OS/2 Warp 4: System default or other outline font. - All versions of OS/2 Warp Server: System default or other outline font. o Simplified Chinese: - OS/2 Warp 4: Song Ti Chang Gui or other outline font. - All versions of OS/2 Warp Server: Song Ti Chang Gui or other outline font. 8. In the Size box, type or select 10. 9. Click OK to close the Font window. 10. Click OK to save your changes and close Preferences window. 11. Close Netscape Communicator. When you reopen Netscape Communicator, you can print the Web page. 2.0 PROBLEM REPORTING AND SURVEY __________________________________________________________________ To report a problem concerning this beta release: 1.
