That is quite a neat trick!
This will have to work as I have had nothing but issues in my attempt to continue reading (from a physical paper back) "On the Origin of Species" with my new Kobo that I just received today. First it would take more than 10-15 seconds to load and then it doesn't even display a completed Table of Contents.
I have used the reset button in the back and done a factory reset through the settings.
Thanks for the trick.
