Overlays; how to turn off grid display only? I have tried to turn off the grid in the overlay options, but when I went to check it off, it was already unchecked.  However, the grid is still displayed!  

The only way I know of to turn it off is to totally turn off overlays, but that turns off all of them, and I don't want to do that.  Can someone help me out?

Edit:
I noticed that the grid check box is greyed out, so what now?
