Although screen captures are something that Windows is capable of doing on its own, third-party screen capture utilities offer a lot more in the way of features. We've tried many of these utilities and have been quite impressed with some of their offerings. ScreenSnag is one of the less intuitive options that we've tried, but it does offer some useful features that make it worth the time it takes to learn.
ScreenSnag's interface is unlike anything we've seen before, and not necessarily in a good way. Its options are all contained within a series of gray boxes; some of these toggle through different options when clicked, while others launch whole separate menus. Mouse-over tooltips explain each button on the interface, but we did miss having a Help file. Once we got used to navigating ScreenSnag, we found that it actually has quite a few useful options; we were able to insert captions and borders, scale the image, and launch images automatically in either our default image viewer or image editor. ScreenSnag provides users with the fairly standard options of capturing the entire screen, a particular window, or a specified area. The timer feature is especially useful, allowing users to take screen captures repeatedly at specific time intervals. Settings can be saved as profiles, allowing users to quickly adjust ScreenSnag for particular tasks. Overall, ScreenSnag wasn't bad, but it didn't particularly impress us with either its features or its layout. There are plenty of other screen capture tools that do both.
ScreenSnag installs and uninstalls without issues.
