After upgrading to 2.3 on my V2 Recorder, when I navigate into a folder and click "Play" to play an MP3 file, it will only play a bookmark (or playlist maybe?) and not the actual MP3 file I clicked on. The same behavior happens in 2.3 on an old JB 6000 I have. If there are no bookmarks in the folder, it just says "End of list" and refuses to play.
I can't find any settings that would appear to control this behavior.
