Can't Print Screen in Paint.

[Ean]

Hi,    Although learning the ropes, I'm still relatively new to Linux. With Windows, when I want to print screen and save the file, I hit Control & Print Screen which puts the image on the clipboard. I then open Paint, Paste, and the image appears and can be saved. The image doesn't appear in Paint when I hit Paste on LL 5.6; please advise me on this. My PC is an HP6005, 2.7GHz dual core with 4Gb RAM, onboard graphics. Ean.
