CaptureWiz will grab anything that's on your screen, in any format, and any size from the size of a dime to full screen. The image can be saved, emailed, put up as a sticky note or just about anything else you can imagine. I have found more uses for CaptureWiz than I can shake a printer at. It's an excellent product and is well worth the modest price. I had a problem with it that turned out to be a problem with my machine rather than with the software, but got excellent tech support on it and got my machine fixed.
Tech support is very knowledgeable and prompt.
