Agiel & GP,

I know what is causing it now and how to fix it (although I don't understand why).

I closed the file without saving and reopened it. I didn't alter any materials, I just deleted the ground plane and the sky displayed correctly. I then inserted a new ground plane and the sky still displays correctly. So the original ground plane was causing the problem, although why it should is beyond me.

Many thanks for your help, if you hadn't sent me hunting for "fade out" colours I wouldn't have tracked down the ground plane as the culprit (even though the new ground plane has the original blue "fade out" colour anyway!)
