Cannot generate or view site using PHP Assistant (OSX10.8.3/FMSA11.5)

I have a mac server and desktop where I have installed 11.x.5 just to be able to use PHP Site Assistant.  I cannot get the "generate" or "view" site to work on either machine (server 10.7.5 w/java 7 21) and on the desktop (10.8.3 / java 7 21).  

When I go through the process (I've done it many times before) and select generate site it opens a dialog box asking where I want to save the site (files).  Regardless of the platform/machine/folder when I navigate to a location the dialog box will not permit me to designate that folder (or any folder anywhere) as the location into which to generate the site.  I can't make it past this dialog box on either machine.

I have reinstalled several times, flushed the java cache, used the full installer (11.0.4.404 or the newer 11.xxx.5 full or the updater) in either case I get to this same dialog box and it refuses to allow me to select a folder into which I need to save the generated files.

This is making me crazy.  Has anyone else run into this?  Sounds like a permission thing, but when it happens on two machine with different OS??  JAVA thing maybe??

The PHP and IWP test pages work fine
