Fanus, naybe try and reset the book courier by pressing the 2 and diamond keys together. Also, if you need to, maybe it would work if you format the flash card, although I would rather try nearly everything else befor doing that. It wouldn't harm the book courier I don't think if you took the bateries out and put them back in. I still have a thing called a road runner, and if their was anything that sometimes used to behave strangely, it was that! But, I also have some strange incidents with book courier, I mean, sometimes, when I quickly go forward or back sentences, it sometimes just freezes and I have to reset, and them it is at a place quite far back in the text, even though sometimes I just tell it to go forward fast!
