Large images are only 100% when the image doesn't fit vertically AND horizontally, not "OR".
The horizontal scroll bar will NOT appear on a large image when "Lock Zoom" is unchecked.
Cannot reset X/Y, period! (meant for large images)
Again, I don't know if it makes a difference, but I tested with a fresh copy of the PortableApps version of XnView.
v1.98: "Fit image to window, small only" is just plain buggy
