Yes, I have had the trouble as you descibed.
I did a complete rescan and changed many settings and the cover art appeared.
I should tell you though the cover art is very small and quite frankly I dont know if it is worth all the effort.
But, now after several hundred more ripped CD's and many rescans later the cover art is gone again.
I cant seem to be able to recreate whatever I did before to get it to display.
Dont bother to call Logitech there help was useless.
