I tried to adjust the line spacing to get more words on the page, but it froze my current book. I can push the n and go to the library and open up another book, but I can not scroll the other books I open, either. The n and the navigation therein are all that are currently functioning. I can not press the middle of the screen and bring up that menu any more. My NST is only days old. I would love for it NOT to be broken. Please help. :\
