CaptureScreen 3.0 was free to download from our software library. The program is included in Photo & Graphics Tools. This free software is an intellectual property of Patrice Zwenger.
From the developer:
Right-click for contextual menu access. Move and size the window to the desired location, and select the "Capture" command for a region capture of the screen, or the "Full Screen" command for a full capture of the screen. Save the capture with the "Save" command; png format (by default) gives a perfect result. The "Clear" command erases the capture.
