Re: Which control for deselectable, mutually exclusive options?

Thanks guys.
I like the idea of a group of radiobuttons with a "Clear selection" button.
Standard buttons aren't generally considered mutually exclusive, and
I'm concerned that some users might not read all of the bumph before
the buttons and might think that pressing a second button means
they've made two selections.
Cheers, Isabel
