I got a nice G5 2.3 DC and a 20" cinema display not too long ago. Now, just recently I hooked up my gaming rig to it to see how it went. Well, I hadn't really noticed it until now: there is a ghost of a menu bar on the top of the screen and of my G5's backround. Is this common in the cinema displays?? It's such a tragic thing to happen to my beautiful Apple display
