DislikedSorry to butt in, but I have a suggestion. Just hit the PrintScrn key on your keyboard. Instantly capture any screen with one key. If you want to capture just the active window, do ALT-PrintScrn.
It's built into XP/Vista and it's free. To save, open mspaint and do ctrl-v. Not as cool as SnagIT but it's free and I like free.
Btw, Jing Project is pretty cool as well and that's free.Ignored
Hope you folks find it useful.
