It /also/ certainly helps to try a non-functioning case of code when being 
pointed to it, rather than complain about being helped. Because that's what 
*I'm* doing when I point out things that don't work: help you. By either 
alerting you to buggy code (code that does not work as intended) or buggy 
documentation (documentation that does not communicate how things are 
intended to work).

Why don't you try it yourself?

Seriously: Why not?

I gave you the best bug-report I can think of writing; with a few discrete 
steps where I describe at each step why I am taking it, what I expect to see 
and what I actually see.

What do I have to do to motivate you to simply follow along with my example, 
see for yourself where things stop working - and then enter that line and 
see it /start/ working. Wouldn't that give you satisfaction? Why are you so 
afraid of simply trying it? What do you have to lose here?

Let me save you typing effort and reproduce the whole file so you can just 
cut/paste it:

// --------------------start here
  #version 3.7;
  global_settings { assumed_gamma 2.2 }

  camera{ location 5 look_at 0 right x*4/3 }
  light_source{<2,4,8>, <1, .8, .6> }

  sky_sphere {pigment {gradient -y}}

  #declare clipper = difference {box {-2 2} box {<0,-3,0> 3}}

  isosurface{function{ sqrt(x*x+y*y+z*z) }
        threshold 2 max_gradient 100 contained_by{ box {-5 5} }
          clipped_by { clipper }
          pigment {rgb 1}
          all_intersections
        }
//--------------------end here

See: I have the best documentation there is: the program itself. Whatever 
the program does is whatever it does. You may /imagine/ that you know it 
better than me, but I've actually looked at it. I get to see the actual 
binary, produced by compiler 'x', using library 'y' interacting with OS 'z'. 
(OS'es are Windows Server.03 32bit and and Server.08 64bit just in case 
anybody really cares).
