The Microsoft Serial Mouse may not work after you exit Microsoft
Windows version 3.0 if the mouse is connected to a dedicated mouse
port. This information applies to all versions of the Microsoft Serial
Mouse and versions 7.0 through 8.2 of the Microsoft Mouse driver for

This problem may occur even if the MS-DOS version of the mouse driver
(MOUSE.COM or MOUSE.SYS) is correctly loaded into memory on the
machine. A designated mouse port is reset upon entering a MS-DOS
application. Upon exit, Windows performs a "soft reset," but some
MS-DOS applications require a "hard reset" of the port. Consequently,
the mouse isn't active in such an application even though the mouse
driver software was installed in memory.
Possible solutions to this problem are as follows:
• If you are using the Windows mouse driver version 7.04 (MOUSE.DRV,
file size 3699 bytes) with PC Tools, call Central Point Software at
(503) 690-8080 and request the files FIXWIN.BAT and FIXMOUSE.COM.
These files will generate a hard reset on the mouse port.
NOTE: PC Tools is manufactured by a vendor independent of
Microsoft. We make no warranty, implied or otherwise, regarding

• If you plug the mouse into the COM1 or COM2 serial port and the
problem disappears, there may be a problem with the mouse port
other than specifically the need for a hard reset. If you plug
the mouse into the COM1 or COM2 serial port and the problem
persists, continue with the steps below.
• In the subdirectory that contains the mouse driver, type "mouse"
. The message "Existing mouse driver
enabled" is displayed. This causes a hard reset of the mouse
port, and the mouse should then work.
• Update your Windows MOUSE.DRV file to version 8.0 (file size 9216
bytes). This reportedly corrects the problem in most cases, but
there are known to be exceptions. This file comes on the Microsoft
Mouse version 8.0 driver update disk. To obtain this disk, call
Microsoft Sales Information Center (MSIC) at (800) 426-9400.
