 Yes. But I don't know why does it happen, the button is supposed to unset
itself as (temporary) default button when it's being destroyed. Can you
please try to debug what happens in ~wxButton of your button? If you can't
find it, please try reproducing the bug with the minimal amount of the code
possible and open a bug report about it on SF.

 Thanks,
