You should have no need to edit this file. Some highlights of the MenuBar object is that timers are used to keep submenus from showing up until the user has hovered over the parent menu item for some time, as well as a timer for when they leave a submenu to keep showing that submenu until the timer fires. *******************************************************************************/ var
