Radio Buttons

[Martin Meili]

Hi
I don't know whether I've understood your problem correctly or not.  
But, just in case, I usually do these things the following way:

on mouseup
      if the hilite of me <> true then
      set the hilite of me to true
break
    end if
    if the hilite of me = true then
        set the hilite of me to false
    end if
end mouseup

Make sure that the autohilite property of your button is set to false.

Cheers
Martin
