I think it's interesting. I tried it on Win98SE and watched memory allocation
with TaskInfo http://www.iarsn.com/ . Everything seemed to keep running smoothly
and minimal change. It leads me to think that it is not the Fritz 7/8 GUI and
maybe Win2000 itself doing this? (note I don't have access to Win2K and my chess
on the same machine).

I'm not sure about "in WIN2000 you can key Control-Alt-Del and run Task Manager"
but you'd want to be sure your observation wasn't due to pausing the process. BK
