Hi,

How do shared libraries work? I read the Flash help file and it wasn’t very clear.

Is it possible to have one external .swf file “LIBRARY.swf” including all the library files I need, load it once onto a root movie.\_level2, then have all subsequent loaded movies rootmovie.\_level1 use the library from LIBRARY.swf?
