 These instructions may be removed but not the above text.
 
 Include this script in your page and open windows with the call:

 SmartPop.up("url", "title", "parameter list" [same as window.open] )

 To close a window, use: SmartPop.up("", "title");
 
 When installing inline event handlers, use the syntax:
 
 <a href='#' onclick="return SmartPop.init()" ....>Link</a>
 
 For unobtrusive event handler assignment, apply a valid ID attribute to each triggering link or other element, then use: 
   SmartPop.init(linkId, "url", "title", "parameter list" [same as window.open] );
   
 These calls must be made at any point below the elements to which they refer. There's no need to involve the onload event.
   
 Ensure all windows are given unique titles.  
   
 At the time of writing, Safari (Win) doesn't redisplay windows when their focus method is called.
