I found a bug related to drawing a selection on a picture while in Fullscreen....
1.) Open a picture to view in XnViewMP (use Win Explorer)
2.) Middle-click on picture to enter Fullscreen view
3.) Zoom into a the picture a little using Mouse scroll
4.) Now draw a small selection on picture (anywhere) using hold left-click and press 'Del' to delete selection...
...Ok normal behaviour so far
...5.) ..But now try to draw a another small selection...BUG
Notice how when drawing second selection it auto draws from top-left of screen in Fullscreen
Please investigate and fix, thanks
