Hello.
In some cases, when I select an area, I need move the selected content, not selection frame.
It would be fine to do it with Alt+Drag combination.
I use AhaSoft IconLover. This program works finу whith ICL files.
And I solved crash problem by exporting files to 16-bit ICL files.
But I hope Pierre will correct this bug with 32-bit ICL.
I understand — there are 16-bit ICL and 32-bit ICL.
In any case XnView should not crash and installed Shell Extension
should not affect Windows Explorer to crash with these files.
