I'm having a similar problem. I can't get the joystick to work at all. No matter what direction I move the joystick in, up, down, right, left, it doesn't do anything, no zoom, nothing. Not sure if it just needs cleaned, or if there's more involved to it than that. You may also want to post in this forum:
