Hi Noel,

that's what I tried with version 814 (the latest update).
Looks like the high cpu usage without responding was a bug in the latest update.

Now after I removed this version and installed the old BB2021 version 804 again it works!
It just doesn't work if BB starts with the wrong chord in the first bar.
So this is probably another bug.
But that's not a big problem if you know how to solve it.. I let BB rebuild the song until it starts with the right chord in bar 1.

Thank you very much!

Best regards,
Franz
