[FF2]

First, I've taken to creating a bookmark periodically as I read in case the K3 forgets where I was in reading. I'd already created a number of bookmarks for this book. I attempted to add another (I have no idea how many already exist). The k3 locked up. I had to hold the power button. When it came back I had lost my place by a bit. I decided to try deleting bookmarks for the book. It again locked up. Another reset and a 3rd attempt and another lock up. On reboot, I left well enough alone - no more attempts

Ideas what is causing the lockups. And where are bookmarks stored so I can remove them all for that book if there is a separate for each book.

Thanks in advance.
