I love my BookPort, but for one problem. Quite often, when I start my player, I find that the player has lost my last listen point and has, once again, started at the beginning of my selection. This anomaly also occurs sometimes after replacing batteries. As I mainly listen to Audible books on my player, this is very distressing. To compound the problem, no matter what I try, I can't advance the recording beyond a sentence or two. Is there a way of locking a bookmark in, so it can't be lost? Is there a setting that will allow me to advance an Audible book by larger segments? Thanks to all for your assistance in advance. Rick
