My Paperwhite is new. I opened a book and now cannot get out of the book and go on to other things. I went to end of book but it doesn't allow me to go anywhere else and has the Before you go... page up. When I use the x in the upper right corner, It has a memo thanking me for downloading the book I just finished. I try to move beyond that and get the "Before you go page again. After a while, the screen comes up with goodreads + Kindle and I try to swipe off this page and it does nothing.
