I have the Rii bluetooth version (RT-MWK02+) and installed "external keyboard support" and "mouse support" to my N900.
The pairing works. Connection works, too (esp. initially) - where the mousepad works fine right after the connection was established. But if I press a key, input seems to loose focus, and the connection is messed up somehow - there are strange key events and the mouse moves uncontrolled.
Does anybody know where to begin to look at in this case?

Regards,
