penumbra.bin - Permission denied!?

[Ozzie]

Is there an in-game way to make a screenshot!?
Don't know how I would be able to do otherwise...

Graphic Card: ATI Mobility Radeon X1300.

I have the latest driver installed (fglrx).

No other applications running that use sound while running the game.

I have to add that the mouse cursor freezes only sometimes in the menu. Can't tell when, though.
