I am using Flex Builder 3 Beta for AS3 development.

When I load an external SWF via a Loader object and generate preview (run) my application with Flex Builder, it does not load an external SWF on the page generated. Yet, when I preview it in a stand-alone Flash Player or via a localhost, it works just fine.

Anyone experienced this issue?

I know it is something to do with the local environment security model. I can understand and appreciate that. However, how do I get control over it in Flex? I cannot add compiler options to Actionscript 3 compiler in Flex unless I’m creating a Flex application. Any help is greatly appreciated. Thanks.
