====== Creating an MDI Child ======

MDI Child windows are those that reside within the MDI client area.  MDI Child windows can be any OpenInsight form created for the current application.  MDI Child windows are often created prior to creating the MDI frame.  A feature of MDI child windows is that they do not contain menus.  Menu functionality is provided by the frame.
