 Usage Notes
   ■ An option button, sometimes called a radio button, displays an option
     that can be turned on or off. Option buttons are often used as part of
     an option group to display multiple choices to the user. Option buttons
     are automatically grouped together when you create and place them in the
     same container.
 
   ■ To group option buttons in a frame or picture box, first position the
     frame or picture box on the form and then place the option buttons
     inside. This grouping allows you to move the frame and the controls
     together instead of separately.
     See: ◄Frame Control►  ◄Picture Box Control►
 
   ■ While option buttons and check boxes appear to function similarly, there
     is an important difference: When a user selects an option button, other
     option buttons in the same group are automatically deselected. By
     contrast, any number of check boxes in a group can be selected.
     See: ◄Check Box Control►
 
   ■ The minimum size of an option button is 1 x 3; dimensions correspond to
     the Height and Width property settings. Specified settings that are less
     than the minimum value are set to the minimum value.
