I put only 2 books on it when I received it (after updated the firmware.) Opened the active one, scrolled past the credits and TOC to the first page of chapter one, then put it to sleep. I might add that I read this same book on my Sony, and it caused no problems at all.
Very disconcerting, but I'm going to wait a few more days before contacting Kobo again.
