Scroll Area resized not always revealing all when scrolling

Also I just noted this is with larger amounts of content, and I have to scroll the wheel to see what's hiding at the top after doing it to reveal the bottom... there is no scroll wheel on mobiles this is not good.

Here is some of the code I use that works fairly well...

        public function resizeTextArea(ta:TextArea):void {
            if(ta != null) {
                var mtf:MobileTextField = ta.textDisplay as MobileTextField;
                var tlm:TextLineMetrics = ta.measureHTMLText(mtf.htmlText);
                ta.height = (mtf.numLines * tlm.height);
            }
        }

Oh heck here's another little give away snippet...

                    var styles:String = timersXML.views.@styles;
                    if(styles != null) {
                        var contentSS:StyleSheet = new StyleSheet();
                        contentSS.parseCSS(styles);
                        mtf.styleSheet = contentSS;
                    }
but I don't think it really matters too much with the behaviour of the scroller versas it's content?

Oh mtf is done like this...

                mtf = targetTextArea.textDisplay as MobileTextField;

One should further note that I'm scaling content scaleX & scaleY via Vgroups and HGroups surrounding everything to manage the size changes between the different devices. So there's likely a mixup in there somewhere.

I imagine again refering to other posts that all this might not matter if apon initialization when calling the MobileApplications spark View creationComplete init function I could see the stage and set the scale there. Still it seems the content on text in a textarea needs to change size to maintain legibility.

So further reporducability details might include to say...

    <s:VGroup id="allGroup" left="8" right="8" top="8" height="614" gap="8" horizontalAlign="center">
        <s:Scroller id="contentScroller" left="0" right="0" top="0" width="480" height="612" skinClass="mycustomclasses.fixas3.VisibleScrollerSkin">
            <s:VGroup id="scrollGroup" gap="4" width="480" height="612" horizontalAlign="justify" paddingBottom="2" paddingLeft="2" paddingRight="24" paddingTop="2">
                <s:TextArea id="contentTextArea" left="2" right="2" top="2" bottom="2" fontFamily="Verdana" fontSize="18" text="Loading..." textAlign="justify" selectable="false"/>
            </s:VGroup>
        </s:Scroller>
    </s:VGroup>
The allGroup is scaled to adjust for the device size changes, and the contentTextArea will have a scale change to undo the parent container, while the height is calculated based on the dynamically loaded content.

But again probable not so much in the details as using the scroll wheel reviews content not scrollable to with the scrollbars or via dragging.

I let you know if and when I figure out any better what's holding deployment back here.

Oh I remember there is also a custom ScrollerSkin related to a previous thread I made for it always being visible, but again not related or important.
