// ****************************JavaScript****************************************+
//  The primary purpose of this script is to create a popup page on command.
//		The popup page will be centered and placed either above or below the 
//		link depending on the location of the page
//
//  This script has multiple functions:
//    	iecompattest() - determines the type of browser and compatability 
//                        with the functions being performed
//		hidemenu() - removes the popup page from the screen
//		delayhidemenu() - allows popup to stay on screen for a period of 
//						  time after the mouse is no longer over the link
//						  The delay parameter is configurable for each popup 
//						  is desired or can be set using "delaystdtime"
//		clearhidemenu() - does some cleanup if old popup is still open
//		showpopup(e,whichpage) - this is the main function that displays the page
//							     e - event, whichpage - is the popup page number
//	*****************************************************************************+
