I am setting the label text, doing some communication over a USB port (which
can take a couple seconds), then setting the text to something else.  I
never see the first label change.  Inserting time.sleep(x) does nothing, but
I am assuming this is a threading thing.  It may work if I do my USB stuff
in a background thread, but that is major change and I don't really want to
get into threading for this.  I have a Label "placed" inside my main Window,
and I don't see any update methods available on either of these. :(

Thanks,
Mark.
