//  NK      14.05.2001 	Close global engine popup when opening a new one!
//  NK      14.05.2001 	Within a same site, append each window name with the session id 
//					   	to resolve session conflict between different sites  !
//  NK      22.05.2001 	If a popup is already opened ( check if its name is equal with the one to open), 
//						give it the focus instead of close and reopen it.
//  NK      30.01.2002 	yO ! another subtil bug found.
//						Added closeEngineWin(), this function should be set on the "onUnload" and "onClose()" event 
//						of any page from which engine popup can be launched.
//						This ensure that when the page is closed or unloaded,any engine popup that is left open is closed !!!!
//						Whitout that, more than one engine can be left open and this means -> possible engine session conflict !!!!
