That is very frustrating... If you load up any other app and press the pedal, does the same thing happen with it going back to the home screen? If so, that would imply that the pedal is sending some kind of command to the tablet to return to the home screen, which is very strange. Are there any other switches or toggles on the donner pedal that can change modes beyond the keys that are sent?
