I have installed all the updates that are available.

Now when I play a file in my Video Library, I can't control it as expected.

If it is paused, and another application has focus, it will resume in the
background.

When it is stopped and Done, it is shown as a thumbnail at the bottom of the
screen with a stop button. MCE will automatically start the thumbnail if
another application has focus. Giving focus back to MCE results in the
thumbnail restarting from the beginning.

How can I stop this behavour?
