The ontouchmove event was being prevented, preventing scrolling while a jquery.menu.js was open. This in general isn't expected functionality.
Prevent the "press" event (and "presshold") from firing the user scrolls via touch events, basically, at all. This causes unexpected behaviors with the press special event listener.
