Must have been a corrupted file. I finally got tired of the bug so I reloaded the patch and the bug disappeared. In fact, the saved game I was on at the start which was 1 visibility was suddenly at 52 visibility when reloaded after the re-patching.

So sorry, Don, but you can't recreate the bug with my saved game anymore as I've redone it several times and the glitch is gone. Foolish me not to go to rule #1 right away which is when in doubt re-load the code.

I was not aware you could change the game parameters like visibility and such. How is that done exactly?

Thanks for the responses.
