Is there any reason why my Freedom keyboard and KBDD should work so ... badly? Using it is about as fun as the on-screen keyboard.

Everything is paired and the keyboard "works", but it's hardly able to keep up with even moderatly competent typing speeds.

I've found either the keys don't register or some get "lost" or duplicated. It's reduced typing to a single-finger "press key, look at screen, press next key, look at screen, correct mistake" effort.
