I'm trying to use the LocalConnection example application to test a few scenarios for Cocomo, and I'm unable to run more than one client instance on the same computer. Once the exception occurs, the entire state of the system seems to be unstable, and I have to restart the LocalConnectionServer. For specifics, it gacks on the startup of the second client with the following exception:

ReferenceError: Error #1065: Variable flash.media::SoundCodec is not defined.
