XnViewMP opens option box in Win 11

[Hans L]

I just installed XnViewMP 1.11.5.0 on a Windows 11 PC and when I open XnViewMP, a window flickers by (very fast; I cannot see what it is), and a box with the following options open in a different monitor: Audio, Drawings, Icons, Photographs, Pictures, Videos.

Can someone explain what is going on and how to get around it?

Thanks,

Hans L
