VIRTUAL SCREENS ?

Hi

Can anyone explain virtual screens to me in greater detail , and help me by
telling me how to move/redraw the image on the virtual screen before
copying the virtual screen back to the screen ?

Can I also only copy a segment of the screen to the virtual screen and then
use it in a "getimage" /"Putimage" way. In other words, can I only swop a
segment of the virtual screen with a segment of the screen ?

Thank you in advance,

If you can help me, please e-mail me at afri...@iafrica.com
