Just take a screenshot, also called a screen capture or screen grab. The Print Screen key will do this, and so will many image editing packages, like Photoshop and Paintsho Pro (which I use). If you can’t get it to work just let me know what particular thing you want to capture, and can email you a GIF or JPEG.
In case you are not sure what to do after hitting the Print Screen key, open Paint and then go to the menu “Edit” -> “Paste” and it should open the screen capture in Paint where you can then Save to the jpg format.
Paint is a minimal graphics application at best. If you find it doesn’t have the features you need, I also recommend Paint Shop Pro.
