Thank you very much for adding the ICN format to XnView

I have a strange problem using it in Total Commander though...
When I switch to thumbnail mode in Total commander (Ctrl+Shift+F1) the ICN files don't appear with their correct thumbnails.
Instead I see the default icon for them. Same happens with .*INT, *.INTA, *.RGBA images (*.RGB and *.SGI are OK)
Could you please support me with a solution to that?

Thank you
P.S. A screenshot:
