My parents just got a new Mac Mini and are having problems with the screensaver. I set it all up for them and have it set for "flurry" to start after 10 minutes. I have to computer set to never sleep (they do it manually at night) and the display to sleep after 20 minutes. So what's happening is that the screensaver comes on and is normal but at some point the picture freezes. In order to get back to the desktop, you have to click the mouse, you can't just move it like you usually would to stop the screensaver. Does anyone else have this problem or know if there is something we have set up wrong?
