For anyone who finds this thread, the problem is friction between buttons 1 & 2 (6-axis arm). While taking hits, I release button 2 with a bit of sideways force. If entering data with button 1, sideways force can pull down button 2 enough that both buttons register. (As Kamikaze suggested) Romer is going to replace the buttons at my convenience. In the meantime, we're turning off the mouse option.
