Thank you Dan for posting this information!
I tried it and it works great of course!

The first data unit I did, with a 200MHz Pentium II MMX, took
91 hours, 28 minutes, & 9.6 seconds with screensaver full time.

The second data unit, with the same system, took
56 hours, 6 minutes, & 43.3 seconds with screensaver blanked!

Its amazing that it took over 35 hours in data unit one to just draw
the dang display!

Do I need more graphics memory? I thought the Pentium II MMX
was supposed to be 'hot' with graphics.

I'm still going to try LINUX as it seems to be even faster!

I noticed too that the seti@home CPU time is just the elapsed time
since the seti@home program stared processing a data unit. So the
CPU Time includes user time when the screensaver is not running
(when the user is using the system).

Thanks again Dan,

Al
