I have just installed the August 2017 patch. I know it has a fix for resizing the popup
All MIM Portal Popups have a fixed size, and the edit controls don’t display correctly.
After you install this update, the popup dialog boxes are resizable, and the controls are displayed properly.
Well now when I go to my IE and click on any object that pops-up in the portal I get what’s below. Completely blank!
Simple, get IE 11, the fix was made for IE 11 which everyone should be on due to security fixes. If you are using IE10 or older you may get away with running “compatibility mode” but the advisable thing to do is upgrade to IE11
