I think what I experienced in 0.82 MP is related to this thread.
Situation:
-- Win10 Home on a touch screen laptop, with XnViewMP 0.82 x64
-- setting of "Auto Image Size" under View and Fullscreen, with "Fit image to window"
-- setting Interface > Mouse, Left button as "Move picture"
-- using the Pan tool by touch
Problem:
-- when the picture is opened, it fits within the screen
-- when I try to pan the picture by touch, the picture immediately zoomed into actual size bigger than the screen and
pan with my finger (given the picture is bigger than the screen),
or the picture immediately zoomed into actual size which is smaller than the screen,
leaving the image unpanned at the center, no matter where my finger goes.
-- when I finished panning, the picture immediately fits back to the screen
-- expected behavior : the picture should not be zoomed from its starting zoom ratio, the zoom should be kept thru out the pan process.
I believe there is a bug in pan tool.
More info:
-- when setting of "Auto Image Size" under View and Fullscreen, with "Fit image to window width or height",
the immediate change of zoom does not happen when one of the dimensions of the picture is smaller than my screen,
at which the panning work as expected. I believe there is a bug in interaction of image zoom with the screen fitting and panning mechanisms.
(this is not always repeatable. Some "X > Y" images with X smaller than my screen_x and Y bigger than my screen_y, the zoom error come back. )
When the picture has both dimension larger than my screen,
the "instant zoom to actual size" come back again, which is not an expected behavior.
-- in fact, I would love to see the XnViewMP response to Pinch command on touchable laptop to zoom in and out.
