Our application is IE specific and works fine up until 11.
When opening pages that contain a modal window to be opened on click, the javascript is carried out immediately and displays the window as part of the main page. On these pages all other javascript relating to menus is also called.
When debugging the js, the only exception is "javascript object doesn't support property or method getchildren()"
This is sorted by compatibility mode but my boss wants it sorted properly. I found ahotfix that looks promising but it mentions neither windows 8 nor server 2012.
Any ideas?
