When using library artworks created in Illustrator in Photoshop the 'placed' versions don't update in Photoshop even when they update in the library

Question

I'm using a Mac and working in Illustrator and Photoshop. Here's my problem:
I would like to be able to add button designs created in Illustrator to my libraries for access in Photoshop. Pretty straightforward - just add the button to the library and then it appears in my library in Photoshop to be dragged and dropped into the file. I would assume that once you drop an item from the library into the page in Photoshop it would remain linked to the library instance but it doesn't seem to which is frustrating. So if I make changes to the original button in Illustrator Adobe then updates the library, but not all the placed instances on the Photoshop page/file. Am I missing something? If not that it is something that should be added.
Any help would be greatly appreciated.

Well, I think I found a workaround, although its ugly and not condusive to a nice workflow :-/
The "Inside Aperture" web page had a blog post describing what I said above, about using Aperture previews as referenced originals in iPhoto: http://www.oreillynet.com/digitalmedia/blog/2007/08/referencedaperture_previewsi.html
And in the comments below, I found this:
+"This works great indeed. I noticed something annoying using this method though.+
+If you edit a picture in Aperture and then open iPhoto which has already the referenced Aperture picture, the iPhoto thumbnail will not update itself automatically...+
+The easiest way to check this is to do a major adjustment in Aperture (i.e. From Color to B&W) and see that the thumbnail has not updated in iPhoto. So far I found two ways of fixing this but it is not really efficient...+
+1 - Rebuild the iPhoto library (long & painful depending on its size)+
+2 - Do an adjustment directly in iPhoto, apply it then revert to the original.+
+With the second option, the thumbnail gets regenerated."+
The bad part of this is then everytime you make an adjustment in an Aperture version and updagte the preview, you now have to go into iPhoto, find that photo, and make a change to it, revert to iPhoto original, (which is now the changed Aperture referenced preview), and the thumbnail gets regenerated. Ugly, and not very automatable .
I am going to try and start an email thread w/ the author of that blog post ot see whether he's found anything eise out.
