Looks like you're spot on, good call. I'd misunderstood the other comment, as you only have to tap the top of the screen once to scroll to the top.

PKUtils.disableScrolling = function (a) { a.stopPropagation(); window.addEventListener("touchmove", PKUtils.preventEventDefault, true); window.addEventListener("touchend", PKUtils.restoreScrollingBehavior, true); window.addEventListener("touchcancel", PKUtils.restoreScrollingBehavior, true) };
