I am encountering a strange problem in my menus. I have 7 tabs in the menu and all the drop downs work fine for everything except one column. The site is www.hamiltonyogainstitute.com. In the menu tab titled YOGA if any of the pages are visited you cannot go to another page from there. You get a 404 error because the menu adds an extra directory path in the title bar. I have used menu writer many times and have never encounter this before. Any ideas on what might be the issue?
