If a Flash .swf if fully imported into a Director movie it
won't be able
to relate to any external .swf files. When a Flash movie
plays by itself
and needs to load in a new movie or data, it reaches out to
level, a server, or a drive's content. When a fully imported
plays from a Director movie, that next level is now the
and so the communication with an external file fails.
In order to keep this relationship between the Flash files,
you need to
link, and not fully import the Flash .swf to your Director
Also be sure that the external .swf files are in the correct
location on the server.
