I'm having a hard time getting AlphaForThumbnail option to work in XnView 1.98.4. :(

I tried few different image file types with alpha transparency, but I don't see any difference between thumbnails when I set AlphaForThumbnail=0 or AlphaForThumbnail=1.

:bugconfirmed: AlphaForThumbnail=0/1 has no effect.

The animated screenshot below shows the thumbnails for spacesuit.png & xnview.png with and without activated Use alpha channel option in the View menu of viewer mode.
