Letter keys don't work

[AlexeyS]

Hello!

I am trying Penumbra: Overture Demo
MacBook Pro 2,2 GHz
Mac OS X 10.5.1 Russian

Any letter keys don't work in the game (default and user defined). Any other keys work properly: digital, arrows, Ctrl, Alt, Command, Shift, Space etc.

When I try to change Key Mapping and press any letter key the word "None" appears opposite the changing function.

I've tried the internal and external bluetooh keyboards. No difference.
