Thanks Adjust. That one is for CS5 (and is rather brilliant). I hear there is a CS5.5 version on the way from Lynda - but wondering if there's anything out there in the meantime.
On another note ...
On exporting a novel from CS5.5 using a simple TOC Style option, it doesn't break the the book into separate html documents. Did CS5? In the training video you linked to above, each entry in the TOC starts its new chapter at the top of the page. Using the same method in CS5.5, the chapters do not start at the top of the page
