Print Screen no longer works

[Maniac]

When I press Print Screen inside Civ4, I get a screenshot of my desktop rather than of the game. Until now I've always gotten an in-game screenshot. I haven't changed any windows settings. Any idea what could cause this?

Using Windows 7.

To list some solutions I've googled but didn't work for me:
Alt-Prt Scr gives the desktop as screenshot too.
Disabling desktop composition doesn't help either.

Perhaps changing DirectX settings, or reinstalling it? That is the first thing I would try.

Civ4 has a built-in screenshot feature, are you getting those images showing up in the screenshot folder?
