HTMLLoader and Scrollbars

Question

I've been following the lynda.com AIR for Flash Devs
tutorial. It shows how to add the Scrollbar Class to an HTMLLoader.
Is it just me, or is Adobe's Scrollbar a rather odd
implementation?
I mean it works, but, for instance, the scroll handle you
grab with your mouse is always much much smaller than it should be
when compared to the actual content.
Also, I have the stage resizing and the scrollbars moving
properly, but I've noticed that resizing the app smaller, always
forces the scrollbar to appear, regardless of the content being
larger than the content area or not.
Is everyone using this implementation for scrolling, or are
people using something else?

OK - my problem with the HTML Control is I can't seem to add it to a child custom class.
i.e. - I have my main Air app and a custom class extending UIComponent. I add the custom class to the stage in the main app, and in the custom class, add an HTML Control.  I'm also adding a different HTML Control to the main app.
Only the HTML in the main app actually shows up. No errors given. What am I missing here?
Main Air app mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.controls.HTML;
var _myComp:Comp;
private function init():void {
_myComp = new Comp();
_myComp.init();
_myComp.x = 200;
_myComp.y = 200;
addChild(_myComp)
var html:HTML = new HTML();
html.htmlText = "Text on main application window"
addChild(html);
]]>
</mx:Script>
</mx:WindowedApplication>
Comp Class:
package {
import flash.display.Shape;
import mx.controls.HTML;
import mx.core.UIComponent;
public class Comp extends UIComponent {
public function Comp() {
public function init():void {
var shape:Shape = new Shape()
shape.graphics.beginFill(0,1)
shape.graphics.drawRect(0,0,200,400);
shape.graphics.endFill();
addChild(shape)
var html:HTML = new HTML();
html.htmlText = "Text Inside child component";
html.x = 200
this.addChild(html);
trace(html.htmlText)
