When I'm on the last page and try to flick forwards, it turns the page back. (Similarly, when I'm on the first page and try to flick backwards, it turns the page forwards.) iIn these situations it should indicate somehow that there are no more pages in that direction, but it is confusing and unsettling for it to turn the page in the opposite direction to the one I indicated. I don't know whether it's the fault of your software or your original pdf, but the fixed width font is badly pixelated and inconsistently rendered from line to line.
