IE11 workflow fix for SharePoint 2010

Depending on your version of Internet Explorer (i.e. 11) you may need to perform the following fix.

Add the following script to your master page.

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


Note: And should be added right above the </body> tag on the master page (in your case v4.master).
