Re: Re: GetBox not called correctly on Linux GTK 3 3.0.2.0?

I can reproduce it.

It looks like it was fixed in wxWidgets some time ago:
https://github.com/wxWidgets/wxWidgets/commit/148971013ee48926dfe153ca39c94be92acde37c

Do you use the Fedora packages for wxWidgets?  If so, I can update them to 
include the patch.  If not, you'll probably have to patch the source 
yourself as I don't expect Robin will make any more wxPython Classic 
releases.
