Shifted area of button sensibilty

[Joost <joost h-labahn de>]

The following code reproduces the problem.
All design is stripped-off for brevity.

This are normally two files, DHead my
replacement of message boxes. DHead.vOutest
is there for adding other widgets thereby
creating more dialogs with all have
a click into the top area as "Cancel".

The problem disappears, when the
set_opacity line is commented out.

This is on WindowsXP, the stable
runtime bundle from gnome.org
with gtk.2.16.6 and pygtk 2.12.

I have the same problem under
depikt (my own python gate to gtk) -
there are more problems in an __init__
for subclasses of gtk.Window().

Thus we have a basic problem with
python here or a problem with gtk,
what is much more probable. Of course
this is a very deeply hidden bug -
that is why i asked only for a
page in some text anywhere.
