Copy Image to Clipboard copies the active window to the clipboard so you can paste this image into other software. This feature is useful when you want to use an image differently than with VIS such as making a poster or preparing a presentation.
To save an image from VIS, copy the image using Copy Image to Clipboard, then start Windows™ Paint and use Edit/Paste to put the image in Paint. You can save it as a bitmap file from the Paint program.
