How do I get scroll bars to work

Question

I get a vertical scroll bar where I don't want one.  The horizontal one (see attachment) is needed as the form gets quite wide when it is in Spanish.  But despite turning off verticalScrollPolicy everywhere, one of them still appears.
<mx:AddChild relativeTo="{bodyFormHolder}" position="firstChild">
<mx:VBox id="resultsPageBox"
backgroundColor="#dedacf"
width="100%"
height="100%"
verticalScrollPolicy="off" horizontalScrollPolicy="off">
<mx:HBox id="rAccessHBox"
    minWidth="640" width="100%"
    x="0" y="0">
</mx:HBox>
<!-- across top *********************************************** -->
<!-- ********************************************************** -->
<mx:VBox id="topResultBox"
    verticalScrollPolicy="off" horizontalScrollPolicy="off"
    width="100%"
    styleName="backColor" >
</mx:VBox>
<mx:HBox id="bothSides"
    verticalScrollPolicy="off"
    width="100%"
    height="100%">
    <!-- first column ***************************************** -->
    <!-- ****************************************************** -->
    <mx:VBox id="leftSideCanvas"
        verticalScrollPolicy="off"
        width="50%"
        height="100%"
        focusEnabled="false"
        styleName="backColor">
    </mx:VBox>
    <!-- second column **************************************** -->
    <!-- ****************************************************** -->
    <mx:VBox id="rightSideCanvas"
        verticalScrollPolicy="off"
        backgroundColor="#dedacf"
        y="0"
        width="50%"
        height="100%">
    </mx:VBox>

Answer 1

A bigger question is how to get the scroll bars to work from the keyboard.  The problem is to be accessible, the application must be available to blind or physically handicapped people that can't use a mouse.
To get the entire form read requires horizonal scrolling in some cases such as when it is in Spanish or the font size it increased a lot.  Now, a horizontal scroll bar appears and is easily movable via the mouse, but we have to have it move without a mouse.
I found the vertical bar came from the form object and I eliminated that, but the bigger issue still remains.
