Finally got it to work. Here are a few snags I solved before it worked. Some of these might have occurred from working on a PC platform, maybe?
1) In the TOC, file links HAVE to be given no extra path. Calibre didn't like it when I had formats with an absolute path like
Code:
<a href="D:\story\file1.html">file 1</a>
or when it was a 'file://' link format like
Code:
<a href="file://D:\story\file1.html">file 1</a>
I also tried with "/" instead which also didn't work.
2) Make sure that each file link is on its own line with no empty lines in the TOC. It has to be exactly
Code:
<a href="file1.html">file 1</a>
<a href="file2.html">file 2</a>
