Thanks for the information. I tried all of the suggestions you gave me and still I have the same problem. This is what I got with only 1 light and no atmosphere. The object was repositioned near the light and still the same problem. I think this has something to do with the object itself, because if you look closely at the counter or top of the microwave, you can see a subtle fish eye effect where the surface is perfectly flat and should not cause such a reflection. One of the worst examples of this problem occured within a room I created. The walls had a circle of light in the center and black around the edges. I had to recreate the flat walls as spline objects to get rid of these shadow artifacts after initially using a plane object.
