Legacy Problem - Radio Buttons (AS1)

A few years ago I built a Flash learning application that used the UI Radio Button component. I have just been asked to make some changes.

Now I am using Flash Pro CS3, and when I output the edited Flash, the Radio Buttons no longer work, as Flash CS3 doesn’t appear to suport radio buttons prior to AS2.

Can anyone provide a simple conversion method, or a way to get the old radio buttons working again? I have tried a few things, but not working.

Need help - FAST :wink:

Thanks
Geoff
