I'm using the Visual Dialog editor to create 2 groups of radio buttons in a custom dialog. Visually all works fine, but all the radio buttons from both Group Boxes are linked together so that when running the dialog, selecting one radio buttons clears all other buttons in it's group and also in the other group. How does one 'connect together' each group of buttons such that they work in independent groups? The buttons are not contained in their group boxes so I can't fathom out to make them grouped.

Andrew
