Re: What the beep is wrong with this?

Hmmm - weirder and weirder.

The actual error code is 1 which indicates a permission problem but I can see nothing wrong in that area.  

I have other "real" stuff on the go right now, but will report back when I get around to fixing this.

Thanks for all the suggestions.
