  /**
   * The only reason this class is needed is because 
   * of a stupid 'issue' with the JTabbedPane.
   * 
   * If the currently selected tab is the first tab,
   * and we insert a new tab at the front, then as
   * far as the JTabbedPane is concerned, NO STATE has
   * changed, as the currently selected tab index is still
   * the same (even though the TAB is different - go figure)
   * and therefore no ChangeEvent is generated and sent
   * to listeners.  Thanks very much Sun!
