Have you tried uninstalling and reinstalling the application?  Maybe a program file has become corrupted.

You can have Windows slow to a crawl for various things, all unrelated to running s@h. Its just that s@h happens to be innocently running at the time.

Of course.  But it slows to a crawl while s@h is running, and when I shut it down, the system immediately goes back to normal.  It has done this several times, and only s@h has this effect. 
I've tried deleting all the stored WU and getting fresh ones, I've tried bypassing SetiGate entirely.  If s@h is running, under any circs I can think of, it's slowing my machine. 
I've started running it only when the screensaver is active, but I'd like to find out what's causing this if I can.
