I was trying off different screensavers (the RSS thingy), and suddenly I press "2" to check some news, and my screen goes black. Not entirely black, just like FrontRow without icons-black. I try to move around the mouse. Nothing happens. I open FrontRow, and hear the sounds, but the screen remains black. I had to do a force reboot, for the first time on any mac I ever tried/saw. This is incredible, my screen simply didn't respond. Has anyone ever tried this before? On a laptop screen or external monitor?
