Thanks Steve, yes I know how to do it, and once i have built the image, so to speak, I click on save and nothing happens, and that is it.
So i expect i have an issue with the program and/or my computer, but the lappy is fine and dose everything i ask of it, so mate i don't know.

Anyway, it is no big deal, just wanted to play around with it.
Thanks for your assistance.
Leon
