[Chameleon] A mixture of radio buttons and image buttons is buggy

[Abe Gillespie]

I have a single toolset that incorporates both buttons with images and
buttons that are just radio buttons.  Moving to the different types of
buttons is buggy.  The radio buttons should completely unselect if one
was previously selected and you move to an image button tool.  Is
there a property or something I'm missing?  This is making my
interface pretty quirky.

Thanks.
