Every so often (often enough to be a concern) my system freezes me out (mouse can be moved but not clicked on anything). If I don't have a large window hiding it, I can see on the desktop that all my icons vanish and are then repainted in place.

I cannot run Task Manager whle this is happening, so that's no help. It happens without regard to my on-net or off-net status. I don't see anything in Task Manager that raises red flags, although I can't say that I know what vsmon.exe and wanmpsvc.exe do.

Has anyone else observed this kind of behavior, or knows what might be causing it?

Thanks,
Richard in Texas
