Drop down menu to left instead of below

Question

HI, I have created a drop down menu in Dreamweaver 8 (since I can't install my CS4).
Anyways everything looks fine and works fine on IE, FireFox and safari when I look at the site but when I sent the link to my client to review the site the drop down for one of the headings pops up to the left on the screen.
I cannot see the problem when looking at the code and I have 2 computers and a laptop and I don't see the problem. But apparently all of their employees see the drop down to the left for the "Education" heading.
Can someone have a look or let me know why this is happening?

The dropdown works for me correctly in FFs and IE7.  However, when I put the page through the validator you get quite a few errors:
http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fcsrt.com%2FNew%2Fen%2Findex.asp
On looking at the code however, I see the javascript for the MM menus right at the top of the document, which is why the validator is throwing the first error..... this is throwing the page into quirks mode and very likely causing the problem with your clients viewing the page.
That js code should be in the head of the document, not above the doctype line....  did you move the js into the document at any time?
You do realise that those menus are not highly regarded and should not be used - read why:
