I tried to follow this tutorial [http://www.kirupa.com/developer/mx/centered\_popup.htm](http://www.kirupa.com/developer/mx/centered_popup.htm)  
to pop up a centered window and need someone to explain a bit.  
I downloaded the finished file from the link and there are three files, fla, swf and html. When I test the fla within flash, it did not pop up a small window instead it opened another full size window and has nothing in it. However when I tested it with the accompanied html, it works fine (a small window pops up in te center of the screen).  
Can someone explain me why?
