FYI, Snapshot/32 was an earlier incarnation of the product which is now known as HyperSnap ver 2.79. The product then morphed into one that could do screen captures from DirectX and other game-related graphics, and became known as HyperSnap-DX. If you don't need the game capture stuff, HyperSnap 2.79 is still available and is a free upgrade to users of SnapShot/32 (www.hypersnap-dx.com/hsdx/snapdown.htm). I've used it throughout several versions and you're right, it's an excellent utility.

>I collected shots of my application for documentation (20 pages) in about 5 minutes. It's extremely easy to use, and had features i wouldn't expect in a screenshot grabber. (the ability to automatically crop the window, the window contents, certain toolbars, etc. was really nice= no 'extra pixel' borders to be cleaned up from one shot to another)
