Have there been double clicks in TV? If you're referring to the menu popping up on every darn item in the view, that have removed by default. Finally... You now have a "play all" alternative on the first or second roller, and you have the option to turn the menu behavior back on under Tools - Options - Theater View - Behavior. On second thought, this might only change things for the Enter key.
J River, why is it so? Why can't this behavior be similar for touch screen and mouse users?
