/*
	E-commerce site version 4.0.0
	-----------------------------
	2008-10-18: Starting upgrade of coding, cleaning up etc. --SF
		* added cmBoundToElement = the element to which the context menu is bound
		* added override_hidemenuie5=false for cpm071 pop-up application (imgmanager widget)

	2008-09-22: Cross-Updated context menus --AJ
	This context menu file requires a few prereq functions, after that you may simply drop it in place and add the 
	following code in your document:
	
		<script language="JavaScript">
		//assign context menu to id(s)
		try{
			AssignMenu('^(d)*node_', 'menu1'); //assigns all ids like dnode_1, dnode_2, node_5 to menu1
		}catch(e){ /* alert if you desire * / }
		</script>
	
	TODO:
	better understanding of load and onload so no conflicts with other pages
	onclick events need integrated as well
