Hi.
I'm quite new to the business of vreating websites, and to this forum, so I hope someone will be able to help me with this problem, which is this...

When I zoom in on my site to see it more clearly in close up, it is behaving very strangely. The content in the RH column starts overlapping the menu, which is in the centre column, and positions part of itself behind the menu buttons. The link for the trial version of the site is:

I'm not sure whether this is a HTML or CSS problem, but I'd be grateful if anyone could spot what is causing this problem.

Many thanks in antiicpation...
