Hi,
I inserted three JRadioButton in my form and I linked all of three buttons to a ButtonGroup. When I preview the form from Preview Design Matisse tool bar button, the radio buttuns doesn't work. But if I run from Run Application from Eclipe IDE it works. am I doing something wrong?

I just asked and got answered on that one. The upshot is that the preview mode doesn't really refect some stuff in code, and radio button behavior is one of those things.
