 *	DropDown Menu 1.2 (Free to use!)
 *	By Evgeny Novikov [java@aladin.ru] [http://java.skyteam.ru/]
 *	It works with IE5.0(++), Opera6.0(++), and Netscape6.0(++)
 *  V1.2: modified 2005-04-01 [http://www.melvinwallerjr.com/]
 *    changed table cell links to anchor links for accessibility
 *    added vertical/horizontal switching
 *    added ability to use images for main menu
 *    added multiple image handling (mouseout, selected, and mouseover)
 * ===================================================================
 * NOTE: The web document must call "menu_data.js" before it calls
 *       this script. The data file is required by this script.
 *       ------------------------------------------------------------
 *       There is no need to Edit this file, all values and settings
 *       should be defined in the 'menu_data.js' file.
 * ===================================================================
