A family of Microsoft word processing software products for creating web, email, and print documents.
I do see the break when showing non-printing characters. The "end of section" setting seems to be working fine, as each chapter's footnotes come after the chapter rather than at the end of the document.
I did notice just now that when viewing the section numbers in the header/footer info that the endnotes for a chapter have the same section number as the chapter that comes after them (i.e., Chapter 2 is section 2, but the page where the endnotes for that chapter begin shows as section 3, the same section as Chapter 3). That doesn't make any sense to me. When I tried creating a new section for Chapter 3 (section 4), the pages with the endnotes were still section 3. I then tried deleting the section break at the end of Chapter 2, but that resulted in all of Chapters 2 and 3 being section 2, and the endnotes for both being combined at the end of Chapter 3. Weird.
The last section of my document doesn't have any endnotes, and when I tried inserting one there it displayed normally at the end of the text rather than on a separate page.
