The information in this document applies to:
WordPerfect® 6.0 for DOS

Problem

Symptoms: The Trackball mouse doesn't work with WP 6.0. Solutions: Testing indicates that WP does have a problem with the MS 8.2 driver that comes with Toshiba laptops. Some customers may experience locking and/or erratic mouse movement with their Toshiba laptop computers and the ballpoint mouse that comes with the computer. This may be caused by the Microsoft Mouse version 8.21 driver that ships with the computer. (This ballpoint mouse works as an IBM PS/2 mouse in WordPerfect and in Windows.) Workarounds include:
1.      Don't load the 8.21 driver at all.
2.      Unload the 8.21 driver from memory with the command MOUSE OFF before running WordPerfect. Note: if other TSR's have been loaded after the mouse driver, MOUSE OFF does not unload the driver; it only disables it. Even disabled, this driver may cause WP to lock, or prevent the internal IBM PS/2 mouse driver from working correctly.
3.      Use the 8.20 mouse driver which ships with Windows and DOS 6 instead of 8.21. (On a Windows 3" high density disk set, this driver is on disk #4 as MOUSE.CO_ and can be expanded with the EXPAND.EXE program on disk #3. For example: copy EXPAND.EXE to the hard drive and use the command EXPAND A:\MOUSE.CO_ C:\MOUSE820.COM. Do not overwrite the customer's 8.21 mouse driver with the 8.20 driver.)
