I think in the paint schemes thread Jav said something like Ctrl + F12, but is there a special menu for that?
(the print screen thing didn't work for me either)
I just tried that and it puts a black layer where the pic should be because it can't read the file, I guess it's fraps for me. is it a one time $37 payment?
I'm using Photoshop Elements 8, and I hit print screen, opened PSE8, ctrl + n, ctrl + v and the layer turns black.
