I've just updated a huge client, and we are experiencing some huge problems with drawnig of GUI.
When clicking edit on Person Interests none of the interest can be seen.
Not until you rearange the size of the windows inside SO Windows. Then all the fields is shown.
I notice, that when the window-size is changed, SO hangs a little, before continueing.
We're using 8.4R04 on a Windows 10 machine.
It's not only in person-interests the problem occurs. The GUI is also missing when adding a link on a sale.
