Snapshot of active window in Virtual PC

Lately, I have been doing most of my work using a Virtual PC and I often find myself having to take a snapshot of the active window (dialog box), especially to create all my blog entries.

I know that Alt+Print Screen copies the snapshot of the active window to the clip board, but in Virtual PC environment RightAlt key acts as the Host key, so if you use the RightAlt key it would not work. So make sure you always use the LeftAlt key to take a snapshot of the active window in Virtual PC environment.
