I saw the option for fbreader in preferences scrolling "large Scrollings". When I change it to tap scrolling. Every time I go back to this menu, it will goes back to "Large scrolling". Bug ??
Other thing that I am wondering, whether its possible to touch the "left half " side of the screen to go back 1 page, and "touch the "right half of the screen to go to the next 1 page".
