Not sure I understand. I think I agree with your description of how it 
works, but I feel it is sufficient for the pad buttons always go to the 
same surface that the pen clicks go to. Do you just mean that the pen 
has a different focus than the mouse? Or are you really proposing the 
the pad buttons may go to a different surface than pen clicks?
