Thanks a lot for trying. You have solved the problem of getting chapter 24 to start on a new page.
But the missing chapters on the TOC are still missing. (I don't mean the TOC at the beginning of the book, but the TOC listed below 'Bookmarks' and above 'History'. Chapter 24 is still unlisted and so are the others that I mentioned before.)
This makes me feel a lot better because it means that I'm not the only one having difficulty with this text. (I was beginning to feel very stupid.) Maybe it is the curse of Dr Johnson. Or maybe BD doesn't approve of very short chapters.
