I could show you my code, but it actually has a bug in it that I need to hunt down and squash. It should be showing the spotlight constantly if you are in the corresponding section of the site but it isn't doing that.
You could probably just as easily do something like for the spotlight to appear:
#nav a:hover {
background-image: url(spotlight.gif) no-repeat;
}
I do this for the menu on my site. To keep the spotlight showing, make your current nav location a new div and then set the image to background. I do that with a color on my site. If you want I can email you my stylesheet for navigation.
Anyway, I love the Dilbert post!!!! We don't get the comic in our local paper, and I miss it so much. This hit the spot.
