Russ,

Many standard Unix directories and files are hidden in OS X.

You can view the /usr/lib/ contents in the Terminal by entering at the prompt:

ls /usr/lib/

Hoewver, here is a little utility I wrote earlier 
to toggle the visibility of such files on and off 
in the Finder.

Since one of your apps continues to work, I'm 
wondering if there may be some difference in the 
plists of the old and new app. I would assume the 
FB code is identical. But I wonder about the 
plists.

        Finder Finagler v.01c

        A small utility to toggle
        the Finder to show or hide
        invisible files and folders
        in OS X.
