As far as I know, none of the Sansa mp3 players support Audiobooks or music Albums with more than 99 tracks. Certainly the Sport and Jam don’t. Do you know off hand if Rockbox does? I will look into it. Thanks for the suggestion. It only takes me a few minutes to fix up the tags of a book by either merging files or going to multiple volumes so I don’t regard this as a killer issue. The lack of resume when in folder mode, except for simple power off and on’, makes it an undesirable choice.
