Grant,
If you are building paths in you code that are relative to your app, please
see my reply to Greg's post. If not, you may as a workaround want to try to
add the frozen application's directory to the system path environment
variable. Windows will look for dlls there, too.
To get the app's actual location, you will need something like the
getAppPrefix() function as per my reply to Greg's reply. The getAppPrefix()
function will also hold when the user adds your frozen app to his/her system
path and call the app from any location from the command line - sys.argv[0]
just won't do the trick in such a setting.
HTH,
