Focus Problem with fullsize video player

Heya,

I’m working with 8.0.30 on a three screen setup. When I have the video player full sized, then I have a focus problem with the arrangement window. I’m in the arrangement window, open a part with enter, close that part with enter, want to open it again with enter, it’s not working because the arrangement window don’t have the focus. If the video player isn’t in fullsize mode everything is working like expected.

Thank you.
Stephan
