Keyboard not working in the FF

[juhaniit]

Hello, for some reason FF doesn't react to my keyboard. The keyboard is fine and operational because I can Alt-Tab back to Windows, but FF doesn't react to it.

I have the same problem with FF straight from disc, FF upgraded to 1.3 and FF from Steam. Other than missing keyboard all versions work perfectly.

(I have 64-bit Vista if that makes the difference)
