It launches and gives me the project window, but crashes when I try to open a file. No such issue in Safe Mode, but that's not surprise since it worked as advertised when I logged into the straw account.

Suitcase does not have to run in the background, but I deactivated my startup set and left only system fonts active same problem, so I don't think it's a font, but rather something else in my user library that's causing it. I even tried quitting PopChar to see if something indirectly font-related was at fault, but no joy there either.

All the other apps work. Go figure.
