When I go full screen in youtube, the prompt that says youtube is now full screen, press esc any time to exit comes up. Often I have to check the box that says to do it every time but the big problem is the prompt popping up constantly through the video. I unplugged the mouse to see if it was too sensitive but it happens without the mouse also. It is distracting and irritating to have this big black box blocking my video constantly. How to make this stop?
