Audiobook won't bookmark
Added an Audible book to it. The nano remembers how far through the book I am until I navigate away, say to listen to some music. When I return to the book, it's back to the beginning.
Turning off the iPod, putting it on hold - the bookmark is remembered. Hit Menu even once and the bookmark is lost.
I checked the book's information and it is tagged as an Audible file, the "Remember playback position" is checked but disabled (so I couldn't turn it off).
Any ideas why the bookmark is not sticking?
