SYMPTOMS

The Microsoft IntelliMouse mouse cursor may freeze or the mouse control functions may begin to fail. You must restart your computer to regain control of your mouse.

CAUSE

The I8042prt device driver misinterprets a valid data packet from the mouse as a self-test return code and waits for additional self-test data. Since this same data packet can be a valid data stream for IntelliMouse, the device driver becomes unstable.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
