Listening to Mouse leavin

Hello, I'm having difficulties implementing a requirement for an
application I'm writing and I'm hoping someone can help.  I have a
JFrame that sits on top of the desktop and has various input fields in
it.  The requirement is that when the user leaves the frame to use
other applications the data is submitted for processing.

I have tried to implement this using a MouseListener.  (I know it would
miss Alt-Tab or other none mouse navigation but I felt it worked for my
user group.)  The problem is that adding a listener on the main frame
fired off an event for it and every component added to it.  So if I
move the mouse across the frame, into and out of a text field without
clicking, I get two events, one when it exits the frame into the text
field and another exiting the text field back to the frame.

Solving the second half was easy, as I knew the only component I wanted
to track, I gave a reference of the main frame to the listener.
However it still fires off an event every time I leave the frame for an
internal compoent, while I only want to track the point it leaves the
outer bounds of the main frame.

I have been stuck on this for quite a while and searched extensively
for a solution.  Can anyone help me, please?  Is there a way of getting
an event triggered only when leaving the outer edge of a frame, either
using the MouseListener or another means.  All help will be greatly
appreciated.
