Control Panel: Rewind

["adam@blueapplestudio" <webforumsuser@xxxxxxxxxxxxxx>]

Coming from Flash I was used to testing my movie (alt+enter) to check it's 
performance.  In Director I thought that the equivalent was pressing Rewind 
from the Control Panel and then pressing Play.  This does not seem to be the 
case.  The Director environment allows you to modify things on stage, and 
pressing rewind does not "reset" all assets.  (Ex: change a texture resource on 
a 3D model to "textureB", stop the movie and rewind.  The model still has 
"textureB" on it.)

 Is publishing the movie the only way to get an accurate look at how it will 
perform?  Is there a different way I should think about the Director 
environment versus the Flash environment in this regard?
