| Handler property holds the name of the script
        function which is executed when the menu item is clicked. Syntax:
          VarioMenuItem.Handler = string Parameters:
          string - Text name of the executed script function. 
           Remarks:The handler function has one argument and no return value. The argument is
        VarioMenuItem object which is the menu item being clicked. Thus you can assign one handler
        function to many menu items and take the proper actions depending on the argument.Initially this property is empty. If you leave it this way, nothing is executed when the
        menu item is clicked.
 If nothing else is specified, the click function is supposed to be in currently loaded
        main HTML file. If several frames are present you should use the HandlerNamespace  property to
        specify in which frame's file is the script function. Example:
          var item;// .... item is assigned a value of menu item object
 item.Handler = "OnFileExit";
 // .....
 // Executed when File|Exit is selected
 function OnFileExit(Sender)
 {
 window.close();
 }
