On all your large scale maps, a vertical ad covers and hides both the maps' eastern edges and the legends on the maps' right-hand margin. The ad is neither movable or closable. I am using the most current version of MS Internet Explorer (yeah, I know, it's probly dumb, but I've finally got my home pages just the way I like 'em and switching to FireFox just seems like a big, risky pain in the tush).
