When I try to scroll beyond 65535th pixel of shown image (ie. 32K on 200% zoom) using scrollbar or "hand" in any direction, viewport moves back at 0 and continues to move again from that point. (If I return back into 64K boundary without releasing button, viewport springs back in right position) When I release mouse button, scrollbar position is set so it matches viewport position. Scrolling using arrow keys is working.
OS: WinXP SP2
XnView 1.92
Reproducible always
