[rules-users] Guvnor 5.3.3.Final version is not loading in IE.

Hi, I am facing problem in accessing the guvnor5.3.3.Final in IE. When I access the Guvnor in IE it just showing the page with "Please wait Application Loading" and nothing comes after that. Application is working fine in Firefox and chrome but not working in IE. I am using the user.agent values as mentioned below. <set-property name=*"user.agent"* value=*"safari,gecko1_8,ie8,ie9"*/> Please let me know if there is any workaround needs to be done to access using IE. Regards, Reddy
