overlapping problem

Now I have also included the Blender file

Hey :),

I try to make a racetrack based on the tutorial of Daniel Sefton.
For the sky dome I use a half icosphere which I have placed around my scene.
I selected all the faces, opened the uv image window and opened up the sky texture.
Then I made a UV calculation ( U -> Cylinder from view).
Then I went back to the UV image and scaled and grabbed the net so it fits the picture.
After several attempts (and hours) of scaling and grabbing, I still having overlapping problems.
What did I wrong?
Can someone help me?

note : I use Blender 2.46

thanks a lot,
Jo Dendauw
