here's a more typically frustrating one - lit source - I do both convert to epub & convert to mobi - I try with and without tickign use auto generated TOC. no TOC appears either way for either output when viewed with calibre reader.. but when I inspect epub code I see h2 tags around chapter numbers !
Code:
<h2 class="calibre2" id="calibre_pb_18">72</h2>
attaching a zip of the source lit - can you get it to convert and to detect & show chapters ?
update - forget that one - it's am embarrasingly bad source, not that I look at it, lots of orphaned page numbers
i'll look for an alternative.
