			 * menuDropdown.js - implements an dropdown menu based on a HTML list
			 * Author: Dave Lindquist (dave@gazingus.org)
			 *
			 * Originally from http://gazingus.org/dhtml/?id=109
			 *
			 * mfischer, 2003.05.07: reworked for own purposes
			 * - Open menus with onmouseover event
			 * - use timeout to closemenu when mouse not over
			 * - renamed all identifier names so we've no namespace clashes
			 *   (lwm - light weight menu)
			 *
			 * mfischer, 2003.05.08:
			 * - use getPosition function to get left/top offset if menu is contained in other elements
			 *
			 * Last time tested: 2003.05.08:
			 * Works in: MSIE55+, MacMSIE51 (OSX) , Win/Gecko, Win/Opera 7.1, Safari 1.0
			 *
