--- Comment #9 from Reinhold reinhold.hoffmann@hotmail.com --- Jeff, thanks for the immediate response.
The software which you used is perfect and correct.
However, it is not trivial to create the failure case. In particular on Ubuntu it is tricky. On macOS Catalina (our main focus) it is very easy to run into the freeze.
I have created gifs to demonstrate the faulty behaviour. Due to their size I have not added them as attachments but made them available on our website to download or view.

The song that I used can be downloaded here. But the freeze happens for any other song. www.notation.com/download/Wine/WineBug_50514/strangers_in_the_night_final_390_measures.mxl
