I agree.  Sizing is probably the trickiest thing to get right in
cross-platform gui code.  Because of the need for backwards-compatability,
wxwin has an awful lot of confusing cruft in this area, so rethinking
things for wxhaskell sounds like a great idea.

Thanks for the quick response (and good luck on getting your thesis done)!

Anonymous CVS doesn't seem to have the fix yet... I'll wait patiently.  :)
