How do you show the flex handCursor in firefox 4?

Hey guys, I'm having a problem with the handCursor component in Flex and Firefox 4.

I've followed the code here to create my handCursor, but it won't render the hand on either my demo or the flex docs. Has anyone found a way to show the handCursor in FF4? If not, what's the best way to handle creating a similar paradigm?

Edit: Here's the code used on both the demo site above, and in a test case I've drawn up locally. Works in all but FF4.

<?xml vers开发者_如何学编程ion="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="useHandCursor:">
                <mx:CheckBox id="checkBox1" selected="true" />
            </mx:FormItem>
            <mx:FormItem label="buttonMode:">
                <mx:CheckBox id="checkBox2" selected="true" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:Image id="img"
            source="http://www.helpexamples.com/flash/images/image1.jpg"
            useHandCursor="{checkBox1.selected}"
            buttonMode="{checkBox2.selected}" />

</mx:Application>

Not sure why its not working in FF4 and didnt checked it, Try to add attribute mouseChildren in IMAGE

mouseChildren="true" 

hopes that work
