Running Windows XP I am finding that printScreen button only captures a black and white image of the full screen but color for just one window (Alt-PrintScreen).

Is there a limit to how much memory can be used for the image that I am hitting here? My screen is huge 2560x1600 pixels, so maybe it drops depth to 1 bit to save memory.

If true, is there a way around this limitation?

Maybe paste it into a different imaging program? Irfanview is great at handling screenshots and all types of images. If it's still broken, then you know it's not your image viewer/editor. – Iain Jan 27 '10 at 0:41
I'm using Adobe Photoshop, but pasting into Microsoft Paint has the same issue. – WilliamKF Jan 27 '10 at 17:44
But only after Photoshop has been launched once since booting. – WilliamKF Mar 26 '10 at 21:19

Seems it was some corruption introduced by some combination of Adobe Photoshop CS4 and the nVidia graphics drivers.

Rebooting and not launching Photoshop after boot and all works fine, once Photoshop is launched, the weirdness starts. – WilliamKF Mar 26 '10 at 21:19

I experienced the same issue on my Windows 7 machine. For me, it was due to a remote desktop session I had open to an old windows server. The remote desktop window was minimised, but it was still interfering with screen shots taken on my desktop.
