Need to make a screen shot in Windows Xp, Windows Vista or Windows 7?

I find that I often make screen shots, either for grabbing colors, background images, etc. With XP and beyond, it became difficult to make screen shots. The "prnt scrn" button on the keyboard didn't just save an image, it put it in the clipboard and then you needed some other software to edit/manipulate it.

Anyway, I found this great program, it's FREE and it will save the screen shot, or even a piece of the screen (you can manually select it) when you hit print screen or any combination of buttons you want. It's a really slick application called Gadwin PrintScreen. This is slick stuff... 

 See what I mean?
