Yes Sarah, I discovered this a long time back. Same thing happens on Linux.
I routinely use handlers to set the hilites of the radio buttons by script.
Actually I lazily trigger these handlers on mouseup as well because it
doesn't do any harm.

It's not what I initially expected to happen and should probably be
Bugzilla'd, though whether it's strictly a bug or an enhancement request
I'm not sure. I'd do it but I think my Rev version (2.1.2) is probably too
old for Bugzilla.
