I'm using the latest version of MusicBee 3.0.
The expected behaviour is that when I double-click a file that's associated with MusicBee, MusicBee will open and that file will start playing.
What sometimes happens is, I double-click a file, MusicBee opens, but it begins to play whatever is the last track I was playing the last time I closed MusicBee.
This doesn't always happen and I can't pinpoint the cause of it.
