| * DefaultDesktopManager policy, MDI requires that the selected |

| * always be the top-most window. |
| * <p> |
| * The maximized state is managed by the DesktopManager with MDI, |
| * instead of just being a property of the individual child frame. |
| * This means that if the currently selected window is maximized |
| * and another window is selected, that new window will be maximized. |
