There was a defect in the last build that seemed to be causing problems for a few users. If you attempted to write to the local database while the program is on a read only medium (like the compressed disk image NouveauPG is distributed in) the write failed silently and users were left wondering why they could not import or create PGP key pairs.
As of version 1.01b, NouveauPG displays a dialog when a write fails and no longer gives any indication that the operation succeeded. Apparently this distribution method is confusing for some, but I have decided to stay with compressed disk images because it seems to be the standard (outside of the app store, of course). Although this method is more confusing, it has always been a goal of this project to produce an application bundle that can be shuffled between computers on removable media.
I have tried to illustrate the installation process below. I appreciate those that have provided feedback, I don’t think I would have found this bug on my own.
