SYMPTOMS
A program that you are running on your Windows NT 4.0-based computer may appear to stop responding (hang).



CAUSE
This problem occurs if a thread in Win32k.sys enters an endless loop while it looks for a window. The amount of kernel time for this program is very high and continues to increase because the thread is almost always actively running in the kernel.
