Without seeing the issue, it's a little difficult. Try this: Turn on hidden characters (I don't remember where this is in 2003; Shift+Ctrl+8 should toggle hidden characters on and off, or it may be in View/Hidden Characters). Place your cursor in the highest paragraph that you think might have the border attached, open the borders dialogue (Alt+O,B is the keyboard shortcut), and see if a border is showing. If so, click none. If not, check the next paragraph.

You can also try selecting a number of suspect paragraphs adn see what the borders dialogue says. If one of them has a border, you should see a wide gray band instead of a black line in the dialogue diagram. Click None.

Does that do it?
