If you try to set a layers url to a resource that throws a security or its missing. Krpano stops working in flash. The URL gets stuck in a loading state. Krpano will still work right until you try to set that url again to something.
I'm setting url with dynamic resources that I have no control over. A graceful fail would be great.
*EDIT* Looks like it dies in flames when using parameters in th URL. No parameters works and throws a krpano security error. That gives at least the possibility of doing workarounds.

And also is it possible to dynamically load the policy file when the domains in the url do not match the domain of the tour.swf file? These CDN domains are dynamic and its a pain to support.
