Try a:
ps -xww

and determine the process ID. Then do:
kill -QUIT <pid>

to get a thread stack-trace on the system console (see
/Applications/Utilities/Console.app). Look for deadlocks.

To force quit from the command line:
kill -KILL <pid>

I'm gonna guess that something you're doing to put up your "inspector"
frame is thread-unsafe with regard to AWT or Swing. You might have to move
that fragment of code into an execute-and-wait task, or otherwise arrange
to run it in such a way that it doesn't block the event-dispatch thread.
