You are not alone.

My symptoms are table width. Some subdirectories expand the table width to twice the normal size. This makes you have to scroll 'length wise' to read the page. I think it's an extra 'table', 'td', or, 'tr' tag being generated within DMOZ. Certain search terms also produce the same effect. The more complicated the page setup, the more likely this problem may occur. Let me know if you resolve the issue. I'll do the same.
