Pop up flash movie - how do I get it NOT to loop?

I have a pop-up flash movie, it works great. Here is the code :

<SCRIPT LANGUAGE="JavaScript">

function jumpUp(URL) {
  window.open(URL,
              "w"+(new Date()).getTime(),
              "width=194,height=146,top=440,top=288");
}

</script>

AND

<a href="javascript: jumpUp('webmovies/flash.swf')">preview</a>

What I am finding out is that is opens a new window, which is great,
but it loops - now I converted the video in Flash MX, but it doesn't
allow me to change the loop properties of the flash video, only the
HTML properties. Is there a quick fix for this using this javascript?
Thanks
