wxRadioBox : start with none selected?

[chris]

Thanks for your reply Tim,

Unfortunately I'd have to tell them: "Please pick one, and if you're
going to pick number one (which is already marked for you), please
choose number two first, and then go back and select number one, so
that I can have it on record that you chose number one."

I'll look into radiobuttons...
