Mouse Malfunctions in MS-DOS Applications

• Microsoft Systems Management Server versions 1.0 and 1.1

SYMPTOMS

When an MS-DOS Application is executed from within Windows 3.1 or Windows for Workgroups 3.11, the mouse will no longer be available or will function erratically.

CAUSE

When a Windows 3.1 or Windows for Workgroups 3.11 client is configured with the SMS client software, the Autoexec.bat is modified to call Client.bat, which is located in the \Ms\Sms\Data directory. Client.bat loads Usertsr.exe into memory in order for remote control to function.

When Usertsr.exe is loaded after the MS-DOS mouse driver, it can keep the mouse from functioning correctly when the MS-DOS application is started from Windows.

WORKAROUND

To avoid this problem, move the MS-DOS mouse driver statement in the Autoexec.bat so that it occurs after the Client.bat statement.

It might be necessary to force the call to Client.bat to be inserted in a specific location of the Autoexec.bat. For information on a method to accomplish this, please the following article in the Microsoft Knowledge Base:
