Is there any way to take a screen shot of my dispaly inverted? When I got back to normal display i look at my saved screenshot its back to normal... This isn't that important. I'm just wondering.

I have a friend with an older Toshiba Satelite T1950CT laptop. Its got I think around a 10.5 inch color display. Problem is, its got "inverted colors". This problem was known when my friend bought it ...
