Certain Flash Not Working Across different Domains

Yes I have a crossdomain.xml file. It reads as follows:



<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy
SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="www.kidpak.org" />
<allow-access-from domain="kidpak.org" />
<allow-access-from domain="www.kidpak.co.cc" />
<allow-access-from domain="kidpak.co.cc" />
</cross-domain-policy>



Just wanted to get that out of the way so no one will start off a reply with "You need a crossdomain.xml file".



Here's the problem....



Some of my buttons will not work if I access the site through one domain versus the other. And it doesnt happen on ALL computers. What's weird is some macs in the office work fine. Others do not. We tried the other campus that has PC's and some work and some dont. I've narrowed it down to how the user accesses the site.



If you go to www.kidpak.org and click KidPak Adventures, then choose any year, you will see our series buttons. None of them work.



But if you access the site through www.kidpak.co.cc, everything works. All my links are relative...not full URL's. We are trying to move away from the kidpak.co.cc domain. But nothing works on the kidpak.org domain.



The server's apache is setup to accept connections from kidpak.org and www.kidpak.org.



This adventures page, when you click on one of those buttons, it loads the specific movie swf onto level 3. That is the main content level.



So any help would be awesome!
