I tested the site on the other computer, the one with the free Zone Alarm, and there was no problem. After a little trial and error, I found that having Zone Alarm Pro set to block pop-up ads ALSO interferes with the menus as I described.
For anyone who is using Zone Alarm Pro and has it set to block pup-ups, if you're getting distortion in the left column of a page, or any where else for that matter, you'll probably have to disengage the block pup-up feature.
