Hi,

Forgive me if this sounds smug, but perhaps one way to overcome this problem is to switch to twin CPUs. I have a dual Xeon system, and after reading your post I checked my Task manager (running Win 2K) to see what was going on. It appears that the screen saver will run multi threaded, because my total usage is about 47%, with each processor doing half the work. I'm not suggesting that you buy a monster system just for a fishtank, but I expect there are plenty of second-hand dual Pentium machnes out there.
