":D" big grin face, so I'm sure Bald Eagle was jesting, at least mostly I'm
guessing.

Having seen your green balloon using that same bump_map... something is
obviously wrong. I think we have all had trouble understanding why it only
happens for you.

Is that version of POV-Ray official or custom?

Probably what we all need to know is at this point is if a test of a simple
normal statement on a simple object is okay or not.

Not knowing what else you've done to check what's going on, maybe forget about
the balloon for now and render this and you should see a bumpy ball (camera NOT
needed! default camera used):

#version 3.7;

global_settings {
 assumed_gamma 1
  }
light_source {
  <-20, 40, -20>
  color rgb <1,1,1>
}

sphere {0,1
 texture {
  pigment{ color rgb <1,1,1> }
  normal { bumps bump_size 1 }
  finish { specular 0.1 }
 scale 0.2
}
translate <0,0,3>
}
