Well I looked at your code, created a local copy of your site here for testing, and fixed your corners and your copyright div:
It was all a matter of the td widths really. Theres some extra bugs here and there (such as 0100% instead of 100%) but I have a working html version of your page tested in both firefox and ie. Im sure you'll know what to change if you're using phpincludes and all that. Also as a sidenote I noted the problems I changed with a big ole PROBLEM marker :-p to help both me and you keep track of what was messing up. Anyways here you are:

<div class="copyright">
<div align="center">This website is copyright Ludwig Wendzich [c] 2005</div>
</div>
</body>
and then to get your copyright div working correctly make these changes in your css:
.copyright {
margin-right: auto;
margin-left: auto;
margin-top: 0;
background: #ebebeb;
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
text-align: center;
border-left: 1px solid #bbbbbb;
border-bottom: 1px solid #bbbbbb;
border-right: 1px solid #bbbbbb;
width: 806px;
}
I hope all works well for you now.

Let me know how it goes.
Edit: Oops, sorry I didnt mean to double post forgot to edit.
Edit#2: If you'd like a .zip of the files I got working lemme know.
