radio buttons and the onChange event handler

[Bill]

Hmmm... the onChange handler for radio buttons only seems to work when I
click on the specific radio button. If I cause it to change - become
unchecked - by clciking on another radio button in the group the handler
doesn't get called. Is this the way it's supposed to work?

I want to set optional properties of certain questions depending upon
whether radion button (a) is clicked or not. Is there some other event I
could set the handler for?

Thanks.

Yes, indeed. I think because checking if there is another radio button that
gets unchecked slows down processing, it is not implemented this way.

You could use the `onchange' handler of the `form' element, or enclose
the radio buttons in a `fieldset' element and use its `onchange' handler.
