Upgraded to MIM 2016 SP1 and popups don't load

Hi,

I upgraded to SP1 on MIM and the pop up windows when clicking on something like "About Forefront Identity Manager" get stuck on loading.

If I clear the browser's cache the pop up load OK--but is that something I'm going to have to tell all of my users to do? Does anyone have a more elegant solution for this issue?

Thank you!
