SpryMenuBar.js

This file handles the JavaScript for Spry Menu Bar.  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.
