I've found what seems to be a consistent problem with the Milestone losing a bookmarked or remembered place in an MP3 book. Using the most current update, I've found repeatedly that when I put the Milestone on charge and leave it until the charge is complete and then unplug the charger, the Milestone reverts back to the beginning of the particular book folder and loses the place I was at within the folder. This seems to happen only when I allow the unit to completely charge, and it doesn't happen if I plug in and then unplug the charger without completing the charge cycle. I've tried locking the keyboard when putting it on charge, but I still lose my place after charging. Jean
