Using SWF and applet java in PHP Nuke

I have a SWF movie with the correlate html code to load it. I tried to save
this code as a .php file ... I tried to open it and all work. Then I took
header.html of NukeNews theme ... I put the SWF html code and I tried to
open it with IE .. and all work ... so I opened Php Nuke, it loads the
entire page except the SWF movie ... and the status bar of IE says 1 object
is loading ... but the loading dont finish! (The same thing appen if I try
to insert an applet java) How can I do?
