[flexcoders] problem using mx:Glow and mx:Box

[mitchgrrt]

I'm trying to put a Glow around a Box, and have the glow show around the 
outside of the Box's borders but not the inside.  Here's part of the code:

    <mx:Glow id="glowImage" duration="1000" 
        alphaFrom="1.0" alphaTo="0.3" 
        blurXFrom="0.0" blurXTo="50.0" 
        blurYFrom="0.0" blurYTo="50.0" 
        inner="false"
        color="0x00FF00"/>
 
    <mx:Box height="100" width="200" mouseDownEffect="{glowImage}" 
           borderColor="black" borderStyle="solid" >

        <mx:Label text="hello" />
    </mx:Box>

The Glow shows up both inside and outside the Box's borders, even though I set 
inner="false".  Does somebody know how to get it to show just outside the box?  
Thanks.
