While we're on Windows 7 and computer tricks- is there a way to selectively disable the screensaver while certain programs are running? I had my screensaver kick in once during a P8 render, and it ended with me having to move the mouse constantly for a half hour while the render finished, screen constantly fading out to black the whole time. Now I've turned the screen saver off, but really don't want to keep it like that.

(I'm running Win7 Enterprise (64-bit) and Poser 8 SR3.)
