SYMPTOMS

When you use Windows NT your mouse cursor may freeze intermittently, but you will still be able to use the keyboard to navigate the desktop. You have to restart the computer for mouse functionality to be regained.

CAUSE

The Microsoft mouse has the ability to reset itself in the event it detects any electrical interference. A reset on the mouse occurs when there is excessive bus noise or other electronic disruptions. A mouse reset is more likely to happen in electrically noisy environments. Some computers may also provide power management to the PS/2 port; this in effect cause the mouse to reset.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.1, 3.5 and 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
