Yes ... just realized this ...
That happens, when you need to reinstall your windows ...
I'm sorry for that ... I hope it's OK now ...

You are not wrong. There seems to be errors in rad calculations when
using background{} color. Replace this:

> background {color rgb <0.0,0.30,0.80>}

With this:

sphere{0,1000
  pigment{color rgb <0,0.3,0.8>}
  finish{diffuse 0 ambient 1}
  no_shadow
}

I think I found why you see a "reflection".
