  possible bug?

the following code gives different results in POV3.6 than in POV3.5 (I tried
to minimalize the code :))

camera{location -z}light_source{-500rgb 1}sphere {0,.25pigment{rgb
1}finish{ambient x*.5specular 1}}

Using POV3.5, I get what I expect: a sphere, with a redish ambient and a
white highlight, but using POV3.6 I hardly get the highlight-part.

The problem seems to be the colored ambient light.  With "ambient .5"
instead of "ambient x*.5" I get the highlight like I expect it.

Another strange thing is that the preview (+sp8 +ep4) shows it the right
way.

I attached the resulting images.

Am I missing something, or is this a bug?

cu!
