afaik, this short example shows that :
- we should delete mc references variables after removeMovieClip() to avoid
holding broken ref vars in mem.
- (ref==undefined) won 't work if we don 't delete the ref manually after
removeMovieClip()
- removeMovieClip() correctly deletes onEnterFrame events affected to an
instance.


trace( "##START ");
trace( "_global.myRef_mc= "+typeof _global.myRef_mc);
trace( "onEnterFrame= "+typeof _global.myRef_mc.onEnterFrame);
//
_global.myRef_mc=this.createEmptyMovieClip( "my_mc ",10);
trace( "##CLIP CREATED ");
_global.myRef_mc.onEnterFrame=function(){};
trace( "_global.myRef_mc= "+typeof _global.myRef_mc);
trace( "onEnterFrame= "+typeof _global.myRef_mc.onEnterFrame);
//
_global.myRef_mc.removeMovieClip();
trace( "##CLIP REMOVED ");
trace( "_global.myRef_mc= "+typeof _global.myRef_mc);
trace( "onEnterFrame= "+typeof _global.myRef_mc.onEnterFrame);
//
delete _global.myRef_mc;
trace( "##REF DELETED ");
trace( "_global.myRef_mc= "+typeof _global.myRef_mc);
trace( "onEnterFrame= "+typeof _global.myRef_mc.onEnterFrame);
