Simon, an interesting approach. If I understand correctly, the issues have not yet actually been resolved, but they are marked as "resolved" based on the fact that the company is now aware of them and has given them tracking numbers. I wouldn't really label that as "resolved", certainly not yet anyway.
With long forum threads, other users are likely to not read the entire thread and instead jump in to try to fix something that they can't fix, which often causes confusion and threads going off topic - I've been asked to mark threads as Resolved to try and prevent that. Unfortunately our forum software doesn't have anything in between Resolved and not resolved.
I was opening a MusicXML a day or two ago and BIAB was still dropping the "Major" from chords and falling back to a dominant.
Can you email that file to support@pgmusic.com to my attention? I'll send it to the devs.
