You may be running into a general problem with displaying UIs from
command line applications. Without taking special care no UI will
work. I don't even think the window server will properly propagate
events to the any UI elements displayed by the command-line
application by default.
If I'm right, you'll have to tell Mac OS X that your command-line
application will present a UI. I think you use TransformProcessType to
do this:
