Well I tried with two different files and get the same result so it must be on my end...

I really don't have the energy to go through another complete BiaB uninstall and reinstall for the FORTH time to see if that resolves my problem(s). I have already wasted several days trying to do a few simple things with BiaB and getting nowhere.

I'll just chalk it up to another thing I cannot do, see if a fix for the inaccurate rendering of MusicXML files ever comes down the pike before the next version is released. In the meantime, I'll use other software to resolve the problem if it ever needs to be resolved in the future.

Thanks again Charlie.
