Critical Error: Internet Explorer 11 and SharePoint 2010

When Microsoft updated Internet Explorer to 11 we started getting the following error on our forms:

” Object doesn’t support property or method ‘addEventListener’ ”

We found that the fix is to add the following java script to the bottom of the Master Pages right above the </body> tag:

<script language=”javascript”>
/* IE11 Fix for SP2010 */
if (typeof UserAgentInfo.strBrowser !== ‘undefined’ && !window.addEventListener) {
UserAgentInfo.strBrowser=1; } </script>

The master pages can be found and edited via SharePoint Designer.

Note: This does not work for Window 8 systems using Internet Explorer 11 for some reason.
