//** Dec 12th, 08" (v1.01): Fixed Shadow issue when multiple LIs within the same UL (level) contain sub menus: http://www.dynamicdrive.com/forums/showthread.php?t=39177&highlight=smooth

//** Feb 11th, 09" (v1.02): The currently active main menu item (LI A) now gets a CSS class of ".selected", including sub menu items.
