Just an additional bit of info which might be of use, JD33:
The more recent versions of Windows (from W7 onwards) all have a useful utility, called the Snipping Tool. You can access it from the Start menu but I find it easier to pin it to the taskbar and then click on it from there. (Its location is Start > All Programs > Accessories. Left-click on it to run it or right-click on it, and then select 'Pin to Taskbar', to have it handy at the foot of your screen).
The Snipping Tool lets you capture part of your screen, simply by clicking-and-dragging a rectangle around it. You can then use File > Save As to save it as an image file, which you can then print, incorporate into a document or whatever else you might want to do with it.
