It's not an omniORB configuration issue. It's a problem with Tkinter.
For some reason, when the Tk mainloop is started from a thread, it
returns immediately, rather than blocking waiting for the windows to
be closed like it should. Perhaps it's a Solaris TCL/Tk problem?

The example only uses a separate thread for Tk because it was
originally used as an example that would theoretically work with all
Python ORBs, not just omniORB. Try removing the code that starts the
thread and calls orb.run(), and put in a direct call to tkloop()
instead. With any luck, that will avoid the problem.

Cheers,

Duncan.
