I'll fix that and reboot. I was watchingSeason 3 of Dark Matter on Netflix on the big monitor and must have got side tracked by the action.

I would have had it if I had realized I was editing the wrong sub volume! Then I deleted it, when I deleted @. 
... OK you can stop laughing now. I used to have a card that said "to error is human, but to really screw up is to use a computer." You would think with all my years of using computers I would notice that. It's always the simple things that we forget and then have to laugh about later when we realize. Thanks for helping me clear it up.

Now that I think of it. Didn't some one suggest that in another thread?
