"Simple printscreen utility."
Works on Windows 7 - 64bit.
There's no "Don't ask next time." or, it's not obvious how to remove the message. Each time you take a picture, it will ask you to cancel or accept. There's no option to always accept no matter what.
Have been using built-in print screen + irfanview for capturing screen for years. But there are times I just need it pre-cut for me (capturing the current window). I have used a pro-version of Snag-It in the past but I really don't use all of the features, and feels a little slow. Gadwin is a very simple tool. Just install, and it immediately works with the print-screen button. Customization only requires a few seconds of your time.
