Hi Stefan,

I don't believe that's a bug - if you mirrored your viewing angle with
respect to the grid then you should see exactly that same highlight on
the cylinder. Specular is viewing angle dependent (unlike lambert) and
a reflection is viewing it from a different angle.

If you wanted to get rid of it plug a raytype switch into your
specular color. Set it to white for primary rays and black for
reflection etc.

Cheers,

Alan.
