Interesting radio button behaviour

[Howard Bornstein]

Hi David,

I'm not sure I fully followed your description but this is what I found.

I can verify that your first point happens on Macintosh systems.
Right-clicking a non-hilited radio button in a group deselects the hilited
button in the group. I guess it's just processing the click and not making a
distinction between right or left clicks.

On your second point, I can verify that when autohilite is off on all the
buttons, a click on a non-hilited button unhilites the hilited button,
whether it's a standard radio button or a user icon. This is what you would
expect. This is normal operation for radio buttons except that it doesn't
hilite the button you just clicked because you've turned off that
capability. I found no difference between buttons that use icons and the
standard radio button in this regard.
