special keys on multimedia keyboard don't work

[copland]

I don't remember seeing this problem in 1.4 versions (since I didn't noticed that, I guess there wasn't such issue), but in RC1 my computer doesn't react on any special keys. I don't have any keys programmed for FlashFXP, but my mail, winamp and browser controls are dead also. In other applications everything's still okay.
This is not a bug, but it's a bit inconvenient to swith to other application everytime I need to skip a track or to run my mail client.
