Thank you, Melanie.

Here is the link to the simplified test site, which exhibits the same problem as the main site (The 'Go' link for the site search function simply doesn't respond to mouse clicks).

In the test site, I disabled all sideboxes and center boxes in order to reduce the amount of HTML code I have to go through when making sure that every <div> is properly closed, etc.

Your help is very much appreciated.

Thanks,
Daniel
