Neither the Print Screen nor the Snipping Tool are working. They have been working fine in the past but now neither one works. Rebooting didn't solve the problem.
Print Screen doesn't seem to put anything in the copy buffer because even though Paste shows up, nothing pastes in.
Snipping tool just shows a black screen with a red border around it, instead of the actual screen shot (no matter which option I select IE Free Style or whole screen, etc) I have Vista Home Premium with all service packs.
