Two questions here:

1. Suppose you run Mac BIAB 2009.5 off the PG-supplied USB hard drive, and -- as PG releases updates -- you download and update that hard drive to run the latest version of BIAB and any updated real tracks. What happens if you later decide to install BIAB directly onto your Mac's system hard drive? You'll be using the installer program that BIAB supplied on the USB drive -- but won't that installer actually be putting an "old" (pre-updated, originally shipped) version of BIAB onto your drive? One would ideally want to update the PG-supplied USB drive so that the active copy of BIAB is updated, AND the PG installer knows enough to install that updated version of BIAB and any updated tracks on another drive, if one decides to go that route. Does that happen automatically when one downloads updated versions of BIAB and realtracks to the USB drive? If not, is any way to make it happen, or an efficient workaround?

2. I'm always confused when I see an announcement in the PG forum that real tracks have been updated. It's easy enough for me to check that I have the latest version of Mac BIAB (build 8 as I write this), but how can I tell quickly if all my real tracks are up to date? I suspect I end up re-installing when I may not need to.
