JRS DHTML MENUS version 1.0 - known compatibility: NETSCAPE 6 and IE 4+ on PC

Change ID	:	WINV030018
Date		:	05-16-2003

Comments	:	Disable Drop Down Feature on Top Nav Bar.

Comments	: Drop Down Menus in Nestcape: The Data Analysis Drop Down in IE has been Left Justified. IT needs to be the same in Netscape also

Change ID	: WIOH030005
Date		: 07-28-2003
Author		: Priority Support
Comments	: Changed letters in the drop down menu should be in Sentence Case

Comments	: The menu has been hiding select elements to keep them from overlaying the menu. 
				This is only needed for IE as netscape selects don't overlap. This change implements
				an iframe modification for IE only that clears up the problem without having to hide 
				the select elements. If we ever need to hide the selects (or any other element) again,
				I've put SELECT_HIDING blocks everywhere where I commented or defeated the select 
				hiding code.
