If I start to read the book (kepub), and page through it all the way to the end, all is fine.
But if I enter the inline toc and choose the first chapter, it goes to the first page of the first chapter, and now show it full page! (no header, no footer, no nothing).
If I page through the chapter it shows every page like that. When the chapter is finished it restarts the book at the cover and all is as usual again.
Interesting....

It's a book from amazon -> Calibre & kindle unpack -> sigil (split chapters into files, created toc) -> Calibre -> extended -> Kobo
I have hade som strange "toc not working perfectly" before in other books (with several different firmwares).
EpubCheck screams at me, I suppose I have made some errors along the way, but it's a interesting feature-enabler I think.
