Url redirection and centered pop-up window

hi everyone, i am using the centered popup window http://www.kirupa.com/developer/mx/centered_popup.htm
in my flash mx movie.
it works fine when i browse to its actuall location (fqdn) on the net (www.itmdesigns.com/portfolio/index.htm) click on the “graphics” link and
try viewing some of the thumbs “>>view”

but i wanted the real url to be masked so i purchased a domain name and
had it forwarded to this location and it seems that the popups dont work
when using masked urls like this one www.risaaconline.com

thanks in advance

also just to clarify, i have tried using both of the following as the address=

on (release) {
address = “http://www.itmdesigns.com/portfolio/popup/graphic/dell.htm”;
//and
address = “popup/graphic/dell.htm”;

Yeah, I have a similar problem at my site www.TheDiabolo.com. The popup seems to work fine for most people in Firefox, but not in IE… I’m not exactly sure when it does and when it doesnt work, but it sure is weird to me. What I do know for sure though, is that it is NOT because of popup blockers.
