If you can't paste your screen into a program, you might want to try Gadwin
Printscreen. It is a small, easy, free program that I use all the time. Here
is the site: http://www.gadwin.com/products.htm?prnscr
This program captures the screen and saves it as a photo to a specified
folder where it can be cropped or edited, whereas Winxp Printscreen just
copies the screen to your clipboard.
I hope this helps.
