I can't believe you're suggesting that my request for a bug-fix doesn't get full priority from the PG Music Team!

I "Print" to PDF files from a BIAB arrangement, and send a copy of the BIAB file itself to colleagues with transposing instruments, so the marker pen isn't a total solution.

MusicReader allows me to annotate my own score after the PDF conversion, but that doesn't solve the problem for the others. They're all BIAB users themselves, so they're familiar with its quirky behaviour.
