I feel like an interloper here, since I don't have a Kobo. But I do design ebooks, and need some advice.

I do all of my ebooks by hand - from Word to valid XHTML to an ePub package which validates with FlightCrew and ePubCheck.

I have just finished an ebook which has a Table of Contents in one of the XHTML files, and this table of contents works perfectly well on my Sony, Kindle 3, and iPad 2 - the human reader can select the link to the chapter, and that takes him or her to the appropriate chapter.

But a friend has read the ebook on a Kobo (I don't know which one) and tells me that the table of contents doesn't work - selecting the link for the chapter has no effect.

Is there something special I need to do to get the ToC which works on on my ebook readers to work on a Kobo? Or do Kobos need a different set up for tables of content than other ebook readers?

Can anyone point me to a reference on preparing ebooks for Kobos?
