I just assembled my e-book (TOC, introduction, 6 chapters and index) in PageMaker 7. In all four of its versions, I had the same problem, namely, a missing link to the index header in the table of contents.
All other links, including the page links in the index itself, are working perfectly well, all other links in the TOC are functional and the bookmarks link to the index header is working, too. In the TOC file, activating the hand tool rendered a link box around the index header. So everything seems to be working fine except that single link in the book, which is a nuisance.
Does anybody have an idea about what could have gone wrong?
