Also found two bugs last night:
1. Have a running playlist with a few songs. When the current running song is just about over, hit the rio stick to the left to begin playing the same song again. If you do this just right at the end of the song (possibly in the silence detection area, this one did have 3 seconds of silence at the end), the Karma keeps the existing track hilighted like it should, but it is really playing the next track. Pressing back again leads the Karma to start over on the wronk track, but keep the correct one hilighted. Only fix I found was to power cycle the Karma, after that, it came back playing the proper song.
2. I had an active playlist of about 160 songs, and saved it as a bookmark. I just left the default name it picked based on the currently playing song. I then went to select a different album to play via playlists (and I did pick a choice from my hierarchal setup), and listened to that for a bit. Went to restore the bookmark, and instead of getting my 160 song playlist with the playback in the middle of a song, I got the 12 track selection I made after it, with the play position at the start of song 1.
