SBO works only with 6 option buttons

Hi all,

I've created a form for definig conditions and added to it 7 option buttons. I've made groups of buttons (2-2-3)with .GroupWith property.Now I've got a problem - grouping in the first group not works. I've spent a lot of time checking various situations and I discovered that SBO make proper grouping only within 6 last option buttons. You can add to your form 7,8,...x opt. buttons, but grouping works only for 6 last. In the XML file I saved my form I see only 2 groups - the first one ignored. The question is - if it's problem only for 6.2 or it's common bug.

Best regards,

Mark
