	Browser problem : Netscape 4+ (only testing on 4.72 right now)
	Issue : Recursion through layers

	I am having a hard time getting a function to reliably recurse
through some DIVs (some nested) 

	I am pretty much at the point where I feel that the Netscape 4.72
doesnt really support this as 	an object as oppose to their <LAYER> tag
(grr) I can recurse through that fine. 
	But DIVs dont work. :(
	Is there a version of Netscape 4+ that this may actually work in ?
Cause I know that Netscape 4+ 	is pretty inconstistent about its DOM model
in these releases.

	I can traverse into the children but then the traversal stops after
one post order point 
	I am not succeeding with a full pre and post order traversal of the

			<recurse in>
				<recurse in>
			<recurse out>
			layer2 --STOP--
		//doesnt pop out to here ??
		<recurse out>
	i am actually trying to emulate ie's flat access DOM in netscape by
storing all the nested layers
	in an array instead of using the
document.layers[i].document.layers[i].document.layers[i]....zzzz 	crap

 document.menu = new Object();
 document.menu.parts = new Array();
 document.menu.names = new Array();
 document.menu.heights = new Array();

var i = 0;
var n = 0;

function buildLayerArray(layerobj){

		for(i=0; i< layerobj.document.layers.length; i++){
document.menu.parts[layerobj.document.layers[i].name] =
			alert("Pre Order" + " = "
+layerobj.document.layers[i].name );
			if ( layerobj.document.layers[i].layers.length > 0
){ //has kids so recurse in
				buildLayerArray( layerobj.document.layers[i]
			alert("Post ORder"+ " = "
