When viewing in full screen (F11) and flipping horizontally (Shift+H), the XnView flips vertically. If I open it (Enter), it does not flip incorrectly.
And if I open, flip and check the "Never ask again" box in the "Save changed file" window, then the next time I start the XnView, this window pops up again.
