When you start up BeanBox, you'll see an empty window. Other builder
tools such as Visual Basic and Delphi refer to the empty window for
building applications as a "form."
When the BeanBox window appears, you'll also see a property sheet
dialog. As you select different beans within BeanBox, the property
sheet changes. New fields and controls are added and removed to the
dialog to reflect how the selected bean can be customized.
