When I use the page up and page down keys, the page number above the slider changes, but the page in the reading window does not. Likewise, when I use the arrow keys or the slider. Then only way I can change the page is by opening and closing the navigation window. I have tried uninstalling and reinstalling, but the same thing happens.
I have the same problem
I also have the same problem.
That worked for me too! Thanks so much!
