I see in the actionscript reference that it ‘may decrease memory required by flash player’ to unload each loaded MC when it’s done, ie when another is loaded over top.

Is this true? And if this is done, does this mean each MC must re-preload before playing, or does the browser cache it (Assuming loaded movies are preloaded)?

Thanks.
