I've been having offline discussion with Steve..... Some people (I know one admin) don't want Prime95 to run unless the machine is *really* idle. These people like a screensaver to run when, in their minds, the PC is idle. And there is no way to change their minds. The machines are theirs. Period. End Of Discussion. A version of Prime95 could be embedded/hidden inside a screensaver. The Photo Album screensaver (GPhotoShow) seems to be a great candidate. We might approach the author(s) of GPhotoShow and ask them to add hooks to George's code. To be perfectly clear, I'm saying that only one program runs: the GPhotoShow/Prime95 hybrid, not one copy of Prime95 and one copy of GPhotoShow. There must be other ScreenSavers we could investigate. --Luke _________________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
