Right-clicking on a selected radical button would set its (visual) status to Related, and thus no longer Selected, even though the underlying radical remained selected. Furthermore, right-clicking on it again would have no effect; there was no way to remove the Related status of a single button, except by left-clicking on it to toggle its selected status. From the comment left in ButtonGrid::radicalClicked(), the original author seemed to have some idea in mind, but left it unimplemented. Right-clicking therefore does nothing, except confuse the user, so let's just disable it. (I'm not ripping the whole thing out just yet, in case someone else want to do something with it.)
