	example:

.movieHandle.loadMovie("myMovie.swf");
.movieHandle._lockroot = true;

_lockRoot  prevents the loaded SWF from malfunctioning.
(if the loaded SWF refers to _root, this makes it refer to it's OWN _root.)


?	_lockRoot gives the loaded movie access to it's own library with attachMovie()

I haven't been able to get *any* movie to access the library of another movie at runtime. The parent can't do an attachMovie of an asset in the library of a child movie, and the child can't do an attachMovie of an asset in the library of the parent movie. The only effect lockroot seems to have is that if you don't do lockroot on the child, then the child can't even do an attachMovie of an asset in it's own library.





	Here is the code I have:

test0 is an asset in the parent library
test1 is an asset in the child library


	Code in parent:
ld1.loadMovie("child.swf");
ld1._lockroot = true;
_root.attachMovie("test0", "junk0", _root.getNextHighestDepth()); //works
_root.attachMovie("test1", "junk1", _root.getNextHighestDepth()); //doesn't work


	Code in child:
this.attachMovie("test0", "junk0", this.getNextHighestDepth()); //doesn't work
this.attachMovie("test1", "junk1", this.getNextHighestDepth()); //works



	If I remove the line, "ld1._lockroot = true;" from the parent:

	Code in child:
this.attachMovie("test0", "junk0", this.getNextHighestDepth()); //doesn't work
this.attachMovie("test1", "junk1", this.getNextHighestDepth()); //doesn't work

	...the attachMovie of test1 in the child doesn't work.
