Whatever I do, I can't seem to disable or change the assignment of hotkeys!

I change 'em and hit "Ok" or "Apply" and the buttons still open whatever they did before - even changing profiles (where the hotkeys should do something different) doesn't alter what the buttons do.

I'd be happy just disabling them (as next to the Shift key, aka BF2's crouch, is the "open media player" key - which, during the heat of battle, is not fun!).

Help?

I've tried uninstalling and re-installing the drivers - didn't help
