[swfmill] embedding as3/flash9 swf problem

[Will]

Hi

so I am having some trouble with embedding .swf files made from .as 
files. I have a simple .as .fla combo with the .fla file using the .as 
class as the base class. from this I get a swf which runs as expected, 
it displays a textfield on a color background.

when I import this into swfmill and try to place it to confirm its 
existence it does not show up.

my swfml:

<?xml version="1.0" encoding="iso-8859-1" ?>
<movie width="500" height="400" framerate="12" version="9">
 <background color="#cccccc"/>
 <frame>
   <library>
    <clip id="Foo" import="AS3build.swf"/>
   </library>     <place id="Foo" name="myFoo" x="10" y="10" depth="1"/>
   </frame>
</movie>


If however I build a flash9 swf from just a timeline .fla then it embeds 
into swfmill just fine.

any ideas why this might be? I hope I am simply overlooking something.

Thanks!
Will
