Hey people.
I've been working more on my website, and improved upon the feedback you gave me a couple of months back.
But now I've got another problem

I've remade the site, with divs rather than tables, and I've been very pleased with the way everythings worked up until now. The buttons at the top of the page have somehow moved slightly and overlapped with the part above it:
http://www.sythix.co.uk/working/
The buttons should look like this:

What's gone wrong?
If you need to know any other info such as code etc, let me know.
Thanks,
Aaron.
