I've had this happen to me twice in two days now. Occasionally when I boot a game, play a bit, then go to the video settings menu, my controller A button will no longer work. Instead of toggling whatever setting I'm on, it just deselects it (removes the highlight). I was using the classic controller, but when this happens and I unplug it, the remote malfunctions in the same way. After it sits there for a minute, I get a code dump.
