For example, I have a clip with an onLoad event that will attempt to loadMovie() the new movie by calling a function similar to the following pseudo-code (this is not the actual code so ignore code errors):
onClipEvent( load )
{
init(); // calls the init function listed below
// NOTE: if I call _root.myClip.stop() here it will work
}
function init()
{
loadMovie( ‘movie.swf’, ‘_root.myClip’ );
