Full Screen Not Available - False Prompt

When viewing YouTube videos in Safari I often get "Full Screen Is Unavailable (Learn More)" warning after toggling that option, but the Full Screen Playback IS enabled, with only the Prompt warning obscuring part of the image. I.E. the video plays in full screen mode but an annoying prompt advising "Full screen Is Unavailable" appears, and can't be dismissed. Is there a way to to remove this frequent annoyance?


Thanks

Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.
