Can you retest this and confirm that it's indeed true? A quick test on my side reveals no such bug.
And I'm guessing somebody would have picked up on this long ago if it was indeed the case.
Edit: You would also need to elaborate on "won't run anymore". What exactly does MusicBee do when you double-click on it?
I already spend hours on end on social media. Might as well spare a few of those to a greater purpose here.
