Thank you for sending that screenshot. I have my workstation set up with a laptop and two monitors. I had my background set to white and I was only viewing Dreamweaver on one of my large monitors. I changed it to a darker color, and I can see the code highlighting. Then I changed it back to white and moved it to my laptop monitor and I can also see the highlighting - so the problem all along was that my monitor wasn't showing the highlighting even though it was there! Thank you so much to all of you for trying to help me figure this out. I appreciate your efforts!
