I'm running iTunes 7.6.2 on a PPC running 10.4.11 I have album art loaded for all my playlists. But when I click on a playlist, about 50% of the time, the art doesn't show (just a blank square). Same if I click on a trick. If I PLAY the track, the album art appears. And, until I quit iTunes, that album art will appear from just selecting that same playlist. But if I quit iTunes, the album art disappears again, until I play a track. Again, this is only for about 50% of my playlists. Help?
