Flash 8 popups

I’m trying to make some links in a full flash site done in flash 8 pop up in new html windows at a set size. My code works fine if I publish to older versions of flash, but not to version 8. I think they changed something for security reasons. Does anyone know of a workaround? Here’s the code that I had been using previously:

on (release)
getURL(“javascript:popupwindow(‘contact.html’,‘contact’,‘height=650,width=475,top=0,left=0,resizable=no,scrollbars=yes’);”, “_self”);
