[Kraftwerk]

I use Calibre, and added a new book to my Kindle yesterday (don't know if this might have caused the problem?).

I have about 150 books on my Kindle.

When I open any book, it shows the last page in the book.
When I turn the Kindle off and back on, the last page I was reading will show, but if I go the 'Home' screen' to look at another book, then go back, to carry on reading the previous book, it shows the last page.

I don't know why this has suddenly started happening!

I restarted the Kindle, but it's still the same.

Any ideas
