MSIE 11 in compatibility mode is causing JS errors because MSIE 7-9 are not good in javascript.


Certain pages on client UI are not being rendered or being rendered with errors.


APM Client and MSIE 11 forced to compartibility mode.


Don't push MSIE 11 to compatibility mode with APM Use browsers that are good with javascript.
