The form has an opacity property. It looks like the panel does not.

I need to have a form with a background image. On top of that image I will have a series of radiobuttons. Each group of radio buttons has to go into a separate container control, like a panel. When I do that, I cannot make the panel background invisible; it covers up my image.

Ok, I could chop up the image and make each of those the background of the panel. Does anyone know an easier way? I would like to make the panel opaque but have the radio buttons show through onto the background image.
