I'm not sure if this is the right section to post this in but here goes. I have this iMac I'll be using for an exhibition and I need my video to play as it should with the "Remain in full screen when player is inactive." checkbox ticked.
But right now it seems like tick or no tick, the video exits fullscreen mode and shrink back to its original size. Is there something I have to do to refresh the settings or something?
