The snipping tool has one limitation (In my use!) It cannot be used to capture a pull up menu. For example, if you want to make a screen shot, for presentation in a forum, of the start menu, this is seemingly impossible, as the start menu vanishes as soon as you select the snipping tool. Apart from this it is excellent.
Fwiw, Kevin, what have you been trying with the prtSc facility?
There should not be a proble. Press prtSc and open Paint, then Paste (top left) or Ctrl with V.
If you want a focussed image of an open window, then Alt and prtSc will capture it. Try it in my comment above. Open your startmenu, Alt PrtSc, open Paint, Ctrl V or paste. Maybe I should menion (?) don't forget to save as somewhere.
