 You currently can't do this in wxGTK (I'd really appreciate if you could
mention your platform (and wx version) as this does not crash under MSW and
so I could have saved the time spent on testing it there). The top level
windows in this port don't support scrolling at all, you need to create a
child wxWindow inside them.

 Of course, there should still be no crash so we should probably add the
necessary checks to prevent it from happening -- unless there is a way of
making wxTLWs scrollable in wxGTK too? Is there, Robert?
