You guys are right -- this is my number one issue with the Mac version of BIAB as well. I also work with longer songs and sometimes add a measure or two here or there, and not being able to scroll normally in the window where I'm entering the chords is a major frustration. It's very unfortunate that PG didn't manage to fix this in BIAB 2013. Is it that major a programming task? I just shelled out a couple hundreds bucks for another Mac audiophile version upgrade, but did so after swallowing hard. I'd be more than delighted if PG managed to address this in an update -- before they come out with 2013.5 or 2014.
