So the mystery has been solved. I'm attaching another sample that uses a VB combo box and removed references to our 3rd party controls in case anyone is interested. The issue was that I was enabling the Option buttons before their containing frame, why it causes this behavior I don't know but if you enable the frame before the controls it works as expected. Thanks for taking a look though and I appreciate the suggestion on setting multiple control group controls.
