Thanks, I added that link to the homepage.

Yes, I just tested, and under Windows 2000 I get exactly the same. This bug is
quite critical, because downscaling is important for dealing wiht large image
files. Unfortunately, I do not know how to tackle it, as under Windows XP and
Linux it both works for me, which makes it unlikely to be a bug in my program.
I might file a bug report against gtksharp, though.

Yes, do not know why, cannot fix.

This behaviour is normal. It shows simple correlation between two images.

Unfortunately, I cannot fix this, too. :-(

Thanks for testing. I will ask the gtk# maintainers to take a look at it, as
they are currently very interested in bug hunting, they might want to give it a
try.

bye,
Sebastian
