When using Pinch To Zoom with on multitouch-enabled screen running Windows 8.1 with Internet Explorer 11 nothing happens. The map seems to be able to get some kind of event as the screen does not zoom, but the zooming effect expected is not present (when using pinch to zoom outside of the map element it works as expected and is zooming). It is working as expected with Windows 8 and IE 10, using that on map would trigger the zooming in and out.

There are two exceptions to this logic:

* https://maps.google.com (is working as expected somehow; zooming in and out)
* https://developers.google.com/maps/documentation/javascript/examples/map-simple (any of the examples using iframe on this page would work; but when opening those with clicking on "full screen" the "pinch to zoom" is no longer working).

What could be the fix for this issue? Judging by how these two places behave there is a fix for that already but it is not being shipped as part of the API.

Looking at this issue, I believe it may be related to changes in IE11 to update to the latest W3C Pointer Events standard:

https://dvcs.w3.org/hg/pointerevents/raw-file/tip/pointerEvents.html
http://msdn.microsoft.com/en-us/library/ie/dn304886(v=vs.85).aspx

Example code I found in the documentation map-simple example that would likely be affected:

function(b){if(b.pointerType!=b.MSPOINTER_TYPE_TOUCH)we(b);else{if(b[D]==hs||b[D]==ks)delete a[b[eo]];else if(b[D]==js||b[D]==is&&a[b[eo]])a[b[eo]]=new U(b[zn],b[yn]);var c=[],d;for(d in a)c[A]({pageX:a[d].x,pageY:a[d].y,target:b[Fc]});b

Here, pointerType now returns a string rather than the constant value used above (MSPOINTER_TYPE_TOUCH is now just "touch"). 

There may be additional places that need to be updated. But this jumped out right away.

It looks like we're also experiencing this issue in a Windows 8.1 Store App. Is there any news regarding a fix?

We are also experiencing this issue when embedding the map into a div. Hope there is a fix soon...

Zoom is working as expected in chrome, not so in IE 11 with the beta / new UI. The old UI works fine with IE 11

Deleted my last comment as this was only true, when the following HTML header is added: <meta http-equiv="X-UA-Compatible" content="IE=10" />

Works fine in 3.16 (even with Metro-style apps)! 
One question, when is 3.16 planned to be released? I couldn't find any information about this online.

3.16 is the current experimental version, which is the default for non-enterprise users. It will become the release version in May.

Thank you very much, I can't wait the release date. I'll go try to use the experimental version 3.16 (lets see if I get the same result #9).
