Err.. It does not do that for me..

Are you sure? I wrote a small test which just intercepts knob left, knob right, and knob pressed. When I try to press the top button, nothing happens.

Here is the bind array I used:

unsigned long data=0, buttons[4] = {4,
IR_KNOB_PRESSED,
IR_KNOB_LEFT,
IR_KNOB_RIGHT
};

Wonder what else could be causing it?
