I have a crossdomain.xml sitting in the root of both static.mysite.com and www.mysite.com:
<allow-access-from domain="*" />
yet I still get Security sandbox violation: ExternalInterface caller http://static.mysite.com/swf/Slide.swf cannot access http://www.mysite.com/.
It seems no amount of loosening of security restrictions will allow this to work. I have complete control over both domains - what's the deal here??
