Since a few days I faced out huge performance issues on IE11 because of the last KB2962872 update.
Have a look at here https://connect.microsoft.com/IE/feedback/details/916652/ie-9-ie-11-freezes-in-some-situations-after-installation-of-kb2962872
With the KB2962872 update on Win7 the performance of Ajax Calls with RadAjaxManager on IE11 is unacceptable.
Performance was even better with IE6, I think!
Maybe someone else has this problem.
So it’s really hard to accept that we all are dependent from this Microsoft crap!
