Captivate 5.5 zoom area shifts from what's in the Zoom Source

Question

Captivate 5.5
Windows 7
Lots of memory and space
I have seen some postings on this topic, but they are either left unresolved or the suggested work around was for a specific user.
I draw the Zoom Source rectangle and corresponding Zoom Destination rectangle. The two drawings match in terms of showing the same content. Yet when I publish or preview the project the Zoom Destination is showing an area NOT defined in the Zoom Source.
My search on this bug seems to return posts from several years ago, and any suggestions seemed to apply to the specific poster, not a general audience.
Thank you for your help.

Hi Handycam,
This warning shows up when you try binding to an object that doesn't implement IEventDispatcher.
Object does not implement IEventDispatcher so any time you bind to a property of that object you will get a warning.
If you define a subclass of EventDispatcher with the properties you want:
MyBindableObject.as:
package {
  import flash.events.EventDispatcher;
  public class MyBindableObject extends EventDispatcher {
    [Bindable] public var label:String;
    [Bindable] public var data:Number;
And then replace the objects in your ArrayCollection with instances of MyBindableObject then the warnings should go away.
SampleList.mxml:
<s:Application
    xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:local="*">
    <s:List>
        <s:ArrayCollection>
            <local:MyBindableObject label="No insulation" data="0"/>
            <local:MyBindableObject label="Fiberglass Batts" data="4.30"/>
            <local:MyBindableObject label="Vermiculite" data="2.4"/>
            <local:MyBindableObject label="Rock/Mineral Wool" data="4"/>
            <local:MyBindableObject label="Urea-formaldehyde foam" data="4.5"/>
            <local:MyBindableObject label="Balsam Wool" data="3"/>
            <local:MyBindableObject label="Cotton Batts" data="4"/> 
        </s:ArrayCollection>
    </s:List>
</s:Application>
