From Brian Scott:
Cropper is a screen capture utility written in C# on the Microsoft .Net platform. It makes it fast and easy to grab parts of your screen. Use it to easily crop out sections of vector graphic files such as Fireworks without having to flatten the files or open in a new editor. Use it to easily capture parts of a web site, including text and images. It's also great for writing documentation that needs images of your application or web site. The files are saved straight to a folder of your choice in the format you specify or to the clipboard or printer. Just double-click the form or press enters, and whatever is visible below the form is captured. The source code is freely available with shared source licensing. The license information is available in each class file.
What's new in this version:
Version 1.9.4 has added single instance option of the application.
