# to reproduce the freeze, right click on the window.  I can't tell if the app freezes,
# or if some window has the focus that should not.  It works ok if you use Show() instead
# of ShowModal(), but of course, that's different behavior.
#
# It seems to freeze when using wx or wxagg, doesn't matter.
