The Madmapper 1.2.3 Interface Screen won't Maximize after Minimizing by clicking the yellow minimize button on the top left of the interface. Also I don't have the misc preference option selected: always minimize on startup.
I had reported this issue last time. So I don't know if this is just my install or if it has happened to other users.
Anyways this can be quite a troublesome issue especially during a live show.
I've had to either quit the whole session and restarted madmapper or gone to delete a preference file in user/Library/Preferences/ com.garagecube.MadMapper.plist.
