Red boxes?

Question:
Why does www.domain.com works correctly and http://domain.com doesn't? Instead of normal images red boxes appear.

This issue is caused by the cross domain policy of the Flash Player. If you see red boxes you probably have a Flash cross-domain security problem. Trust me, I know it can be frustrating. When loading bitmap data from another domain (or even another sub-domain), you need to use a cross-domain policy file to tell Flash that all is ok.

Flow List is set up to check for the crossdomain.xml policy file at the root of the domain (i.e. http://www.yourdomain.com/crossdomain.xml) from where you are loading images.
