A problem has occurred during button detection.
Multiple mouse buttons have been detected. There are three possible causes:
1. You pressed different buttons too many times. Press Cancel and try again.
2. You pressed a previously detected button too many times. Press Cancel and try again
3. Your mouse button sends more than one event when pressing that button. btnx cannot handle more than one event during a button press. You must choose one rawcode below to associate with that button.
(Hint: choose the one with the most clicks. If there are multiple rawcodes with the same number of clicks, try one and see if it works. If it doesn't, try another one next time.
