Thank you for your response. Your code did in fact fix all issues other than the HOME page with Internet Explorer 7+, 8+.
When you go to www.hobsontravel.com and hover your mouse over Leisure Travel or Business Travel you should get a fly-down menu but don't from the HOME page.
Strangely, when you click on ANY of the links other than HOME, the menus work as they should once you get to that page.
I have tried changing the path structure of the primary index.html file, both hard coding and canonical path and still no luck.
Any ideas as this is ticking my customer off a bit.
Thank you very much,
