		window has been invoked, it should not allow for another child window in pending
		login mode

		comparison instead of "=".


	Modified by: Ho Sheh Pien, Citibank N.A.
	Date: 30 May 2000
	Desc: - modified LogoffAll() to avoid prompting of authentication extension if it is
		a guest logon in ALERT service


	Modified by: Ho Sheh Pien, Citibank N.A.
	Date: 1 June 2000
	Desc: - modified DetectService() to create _HPLogonWin_ only is _ACCESSID_ cookie exist 
		rather than _ACCESSHOST_ cookie
	      - added alerts to detect for AccessID and AccessWindow

	      - removed unnecessary commented codes
