SnapShot/32 version 2.55 from 1994

As you would expect, the software is no longer available, but it has worked
WELL through all my Windows versions. It is a GUI driven screen capture utility - allows you to capture a: window, rectangle, desktop and save it as: bmp, jpeg, gif or send directly to printer.

The built ins and newer apps aren't as easy to use, and I have captured items with this utility that I would not have been able to with others.
