When playing a file using the built-in player, MBP is unable to save any queued changes to the file. While this makes sense, the only other playback control is “Pause”, which doesn’t release the player’s lock on the file; paused files can’t be saved any more than actively playing ones can.
Currently, the only way to release MBP’s lock is either to allow the playback to reach the end of the file, or to play a different file. Obviously, neither of these solutions are optimal. What MBP needs is a simple “Stop” button, to both cease playback of the file, and to release the lock on it so it can be saved.
Thanks for a freakin’ AWESOME product!!
