When I watch a movie in Movie Player, the HUD pops up every 8 minutes or so. I am not touching the keyboard or the mouse at all. Alt makes the bar go away, and then 7-8 minutes later, it pops up again. This happens when I'm watching fullscreen or not fullscreen.
Can you help me fix this? I've been using VLC instead (because it does not have this problem), but I don't like it as much as Movie Player.
