I've contacted Seti @home about this in the past and got no response from them. Thier client program uses ALL unused CPU cycles available and releases only what is needed by other programs. But if the other program is a 3D screensaver, the client doesn't release CPU cycles and the two programs lockup.
In short, if you are going to use a 3D screen saver, you can't run Seti@home. The exception are the excellent screen savers found at http://www.reallyslick.com/ which are really cool and free.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
