website menu shifting

[giyn]

Hi all - I knew I already posted a similar post here but I just wanted to explain it further. I'm new to web destign. Recently I did a website for a client and he complained that the website on his computer doesn't appear properly, but I have no problem with it (I've tested it on about 10 computers and the site appears okay). My client is using IE (window 7). I have no idea why it only happens to his computer.

Please help and thanks in advance!

What's the url for the website? (If you can't post the url because you're a newcomer, just type it with a space in the w ww).
