MS Surface touch events not recorded - scrollbars not moving in IE10/Metro

[esumm]

Testing on MS Surface Pro w/Windows 8 Pro, in Internet Explorer 10 METRO mode.

jquery=1.10.2
scrollbars = latest

I've tried manipulating the '-ms-touch-action' CSS variable, but to no avail. Tested same page on iPad, worked flawlessly.

thanks! (great plugin, yo!)

wow...looks like IE10 really pulled a 'microsoft':
http://msdn.microsoft.com/en-us/library/ie/dn433244(v=vs.85).aspx
*(of COURSE ms can't use common/standardized touch-event-listener names...they had to make up their own...ugh)

I don't have access to such a device but it looks like they have an emulator http://blogs.msdn.com/b/patricka/archive/2012/07/23/how-do-i-test-internet-explorer-10-touch-behavior-without-a-touch-device.aspx
I'll try to get it and check.

Hi mzubala ,

I have done some changes in jquery.custom-scrollbar.js and now it is working absolutely fine in IE 10 touch devices.

Here is the solution. Just replace the jquery.custom-scrollbar.js code below code.

(function ($) {

$.fn.customScrollbar = function (options, args) {

var defaultOptions = {
  skin: undefined,
  hScroll: true,
  vScroll: true,
  updateOnWindowResize: false,
  animationSpeed: 300,
  onCustomScroll: undefined,
  swipeSpeed: 1,
  wheelSpeed: 40,
  fixedThumbWidth: undefined,
  fixedThumbHeight: undefined
}

var Scrollable = function (element, options) {
  this.$element = $(element);
  this.options = options;
  this.addScrollableClass();
  this.addSkinClass();
  this.addScrollBarComponents();
  if (this.options.vScroll)
    this.vScrollbar = new Scrollbar(this, new VSizing());
  if (this.options.hScroll)
    this.hScrollbar = new Scrollbar(this, new HSizing());
  this.$element.data("scrollable", this);
  this.initKeyboardScrolling();
  this.bindEvents();
}

Scrollable.prototype = {

  addScrollableClass: function () {
    if (!this.$element.hasClass("scrollable")) {
      this.scrollableAdded = true;
      this.$element.addClass("scrollable");
    }
  },

  removeScrollableClass: function () {
    if (this.scrollableAdded)
      this.$element.removeClass("scrollable");
  },

  addSkinClass: function () {
    if (typeof(this.options.skin) == "string" && !this.$element.hasClass(this.options.skin)) {

    if (this.$overview.length == 0) {
