Suddenly with Calibre I am not able to produce a functioning table of contents on the resulting LRF ebook when I start with a LIT ebook. The TOC in the LIT ebook is functioning, but the TOC in the LRF conversion does not work. When I test it on my Sony, the TOC items are listed on the TOC screen but clicking them does not take me to the chapter. It just goes to the first page of the TOC.
A couple weeks ago, I did successfully make LRF ebooks with functioning TOCs from LIT files.
Yes, I am checking the box "Add chapters to TOC."
Any ideas on why it does not work anymore?
