When I set a book mark in a RFBD DAISY book, the mark always takes me to the beginning of a section or sub-section. I cannot use the go to book mark command to go to the place where I wanted the mark to actually be placed. Often there is a significant amount of reading before I hear the part of the book I really need to review. In other words, the mark seems to be placed somewhere in front of the place where I expect it to be placed. Any feedback? Jim King
