IE11 causes website to freeze in some scenarios

[JDK (Josef R.)]

Hi all

We are at my workplace facing problems after IE upgrade from 10->11

Sadly website is Secure and i cannot share any images or codes.

But I Will try to explain the scenario:

Robot Will type Into postal and streetname inputs and submit this form.
Form Will run API to try and verify postal and streetname and if succes it Will return datatable of possible streetnames available.

In some scenarios where returned DT contains Many possible matches we face issue when selecting adress.

IE seems to freeze and never return back to useable State.

This works perfectly in IE10.

I am unsure what more information to share - but please ask for anything Else if needed.

I hope someone have any ideas - this is my last resort.
