Well the easiest solution is simply to put the controller on a table instead of on your lap !
Yeah raine reacts to any "stick" in the gui, the code is from before game controllers so there was no way to identify a movement to know from which jostick or button it came, and so it reacts to any stick movement. I guess I could at least remove this now so that for game controllers only the left stick is handled for that. I'll do that.
