flexlib.mdi does not return to previous cursor after window resize.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile the application below 
2. Notice the spinning busy cursor
3. Move your mouse to reset, or just mouse over the edge of the mdi window.
4. A normal cursor is presented, but I expect it to go back to busy.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" 
xmlns:ns1="flexlib.mdi.containers.*" 
creationComplete="onCreateComplete();">
    <mx:Script>
        <![CDATA[
            import mx.managers.CursorManager;
            private function onCreateComplete():void {
                CursorManager.setBusyCursor();
            }
        ]]>
    </mx:Script>

    <ns1:MDICanvas width="100%" height="100%">
        <ns1:MDIWindow x="73" y="59" width="294" height="229">
        </ns1:MDIWindow>
    </ns1:MDICanvas>

</mx:Application>

What is the expected output? What do you see instead?

I expect the busy cursor to come back, but instead I get a pointer

What version of the product are you using? On what operating system?

Flexlib 2.5 for Flex 3 on Windows
