Software freeze

This is a repeat of a post from a year ago that went without a solution being posted:
Whenever I try to preview a video I end up with a preview box bigger than my screen that I can’t close since it seems the controls are outside the area of my screen.

I end up having to end the process as I can no longer interact with the program.
Anyone know why or what I can do?

Hi there,

You can close the window with Alt+F4. That’s the way I do it.
