PASSCo's "Hold" Page or Window 
(This screen is refreshed to itself ever three minutes to hold the ISP connection)
  First try to return to a prior page. Else  this pop-up window.
--- Using close when not a pop-up window will close your browser. --- 
   You are viewing PASSCo's Generic "Hold" Page or Window. You are here due to one of three situations.
   First, you may have clicked on the "Hold" icon, PASSCo utilizes many "dynamic page presentations" which are pages that "timeout" and "refresh" to another defined page. Thus, clicking this icon produces this "hold page". When the "Back" button above is clicked, the calling page reappears, and the series of pages again proceed as designed.
  Second. PASSCo uses this page to present a page yet to be developed, or pages that may no longer exist. Clicking "Back" returns you to the calling page.
  Third. PASSCo uses this page as a pop-up window. Pop-Up's do not respond to the "Back" Button. Use "Close" to return to the calling window. Try "Back" first
Clicking "Close" when the page was not a pop-up window closes your browser.
