    • Works fine unless you have a precision trackpad… this is essentially a duplicate of this long-standing issue:

    • Bryan,
      I think it’s a different issue. This is interacting the screen directly via touch, not with the trackpad.

    • The issue where it won’t scroll when using Touch is Adobe’s bug, not Edge’s… Easy to fix too. They just need to listen to Pointer events instead of only touch events, or use a shim.

      The issue where it won’t scroll using a precision touchpad on the other hand IS a bug in Edge as Edge does not fire wheel events from precision touchpads, nor does it fire any other events… There’s no way for Adobe to work around that until Edge is fixed.

    • Adobe’s site does actually support Pointer Events (and works in IE11 as a result), but is using browser detection and UA sniffing as part of their determination if the browser supports touch:

      a.isIE = !!document.documentMode,

       

      a.pointerEventsEnabled = window.PointerEvent || window.navigator.pointerEnabled,
      a.msPointerEventsEnabled = window.navigator.msPointerEnabled,

       

      a.touchEnabled = a.touchEventsEnabled || (a.msPointerEventsEnabled || a.pointerEventsEnabled) && a.isIE && b.search(/touch|mobile/i) >= 0
      || a.supportsMozInputSource;

      Later, if the touchEnabled property is false (as it is in Edge due to the logic above), the touch drag tracking is disabled:

      WebPro.touchEnabled || a.tracker.disable(),

      To fix this, Adobe will need to relax the check to ignore isIE and the UA string, like so:

      a.touchEnabled = a.touchEventsEnabled || (a.msPointerEventsEnabled || a.pointerEventsEnabled)
      || a.supportsMozInputSource;
