shows album art where in the album art view in the list view area?
or in the album art window you can open by clicking view menu.
or on the player where there is an album art view area on if you use a player that has album art view?
by not showing do you mean it is not showing anything at all even the no album art image is not showing?
or just the song's cover art is not showing, and you do see the no album art image.?
there are so many places to see the album art we really need it narrowed down to which and what?
