yes, cookies would be the best way to do it, but a little complicated.
the easiest way is to frame your site and have the pop-up script in the frame sorce .html file.
or, if you don't pop-up any recurrent windows, you can simply have the first popup going into the same window in the background, even if the script is triggered several times
Code:
PopUp=open('popup.html','popupwindow');
PopUp.blur();
self.window.focus();
