1) Script Title: DD Tab Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/ddtabmenu.htm

3) Describe problem:
(I am using the menu with the horizontal submenu, not the dropdowns.)
I needed to make a slight adaptation to the code: I omitted clearing the tabcontainer because I have floats to the left of the navigation that I did not want to clear just now. Now I get inconsistencies across browsers with margins on the element that displays below the navigation. IE displays the next paragraph below the horizontal submenu and Firefox and Safari display it as overlapping with the submenu. What could be the problem?
Thanks
