Looks like the state machine inside the keyboard gets a little bit crazy 
when you press the third button. The data that HID core sees coming on USB 
bus really don't represent [right,down,left] being pressed.

Do you have any chance to verify whether this works properly in a 
different operating system? It would require very specific handling 
violating the standard.

Thanks,
