wxWidgets-related question

[Sergio Had]

Does anyone know what is responsible in wxWidgets 3.0 for dialog windows handling, and specifically buttons in those like Okay?
Those are broken on 10.6 for me: any dialog window which opens does not respond to Okay or Cancel at all.

Everything works fine on 10.8 though, from the same port.

I briefly looked into patches we apply, and nothing appears relevant to the matter.
Perhaps a bug in the upstream code, due to lack of testing for < 10.7. As usual.
