Max, That is exactly the problem, NO process is taking the ticks. Often even SQL Server is not taking the ticks. The CPU usage is almost zero, but the cursor won't move, Alt-Tab takes 15 seconds before it switches and even thin it is more seconds before the screen redraws. It is like Windows executive itself is out to lunch. This is the strangest thing I have ever run into. John W.
