Cover Art refuses to work on Clip Sport with Ogg Vorbis, works fine with AAC

This is really annoying, I would have hoped Sandisk would have fixed this already, but I have tried embedding, folder.jpg, albumart.jpg, and none of them work.  my Fuze+ refused to work with Ogg Vorbis coverart as well. What is up with this? Why isn’t this working? I really need some help here.

What is the size of the album art? I found this in one of the KB articles

http://kb.sandisk.com/app/answers/detail/a_id/221/kw/clip%20sport%20album%20art 

Note: The SanDisk Clip Sport album art maximum supported resolution is 480 x 480  with a maximum file size of 450kb

If you album art is within that spec and still not working can you post a sample file?
