There are two versions of FinderMenu in this release - the version written completely before MacHack (which was uploaded to Compuserve, and comes with Installation files for Frontier) And the version that I worked on (a little) during MacHack.
The later version combines the FinderMenu App with the FinderMenu INIT and fixes a few bugs. It's called FinderMenu 1.1a1.
The stable, tested, release version of this stuff is FinderMenu Release ─.
