Header: Two small adjustments

  1. For the logo, the increase looks good, but could you now decrease the width by a hair's breadth. Sorry to be such a nitpicker about this.
  2. For some reason, when I mouseover the nav tab of the section in which I am, it disappears. So for instance, if I'm in About this Site, then this happens to the About this site nav tab only. I'm not sure we need this to be happening.

And everything here resolved. Again, thank you!
