1) Script Title: jQuery Multi Level CSS Menu #2

2) Script URL (on DD): http://www.dynamicdrive.com/style/cs...el_css_menu_2/

3) Describe problem: I've built a site using this menu but every time the menu loads it stutter from left to right. Link below shows the problem. Click on links to see. Also the last divider is thinner than the others. Any reason for that as well please. Thanks for any help.
