I think another error from a prior release has slipped through regression testing... I could not find the thread, but there was a problem reported some time go that I have seen three times now with the latest stable release, 4.5b SR-3. You do an "Add book" under Personal Books, and you are adding info to the fields. If it just sits for about 10 seconds, the entry just closes itself, leaving a partially completed entry in the list of personal books. You have to find it and continue editing, or delete it.
