Website protrudes beyond the 800 pixel wide limit on right, in IE

Question

Hi - please help me with this, somebody - it's driving me mad. the URL is http://www.wuizmendez.co.za. I know enough to be dangerous, and am on the point of leaving the more complicated bits to a 'real' web designer. My problem is similar to someone who earlier who had the six nested tables. :O
But I can't locate the source of the problemo.

Answer 1

Nope, that isn't it either. So (what I should have done in the first place) I checked a page (Course 3) within DW by hitting the 'check page' button for browser compatibility.
(Have subsequently come to a few fixes, so ignore the gray text unless you're already bored/compulsive) This is just background.
And it said in the left panel:
that there was a problem in line 15 (see below in bold) and in the right hand panel is said:
Found 3 errors in external css files
Affects: Internet Explorer 6.0; Internet Explorer for Macintosh 5.2
</style>
<script src="Scripts/AC_RunActiveContent.js" type="text/javascript"></script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Wuiz Mendez | Course 1</title>
<link href="wmstyles.css" rel="stylesheet" type="text/css" /><script type="text/javascript">
function MM_CheckFlashVersion(reqVerStr,msg){
  with(navigator){
    var isIE  = (appVersion.indexOf("MSIE") != -1 && userAgent.indexOf("Opera") == -1);
    var isWin = (appVersion.toLowerCase().indexOf("win") != -1);
    if (!isIE || !isWin){ 
      var flashVer = -1;
Then I checked Course 1 and it said the same thing but this time in line 20:
Found 3 errors in external css files
Affects: Internet Explorer 6.0; Internet Explorer for Macintosh 5.2
</style>
<script src="Scripts/AC_RunActiveContent.js" type="text/javascript"></script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Wuiz Mendez | Course 1</title>
<link href="wmstyles.css" rel="stylesheet" type="text/css" /><script type="text/javascript">
function MM_CheckFlashVersion(reqVerStr,msg){
  with(navigator){
    var isIE  = (appVersion.indexOf("MSIE") != -1 && userAgent.indexOf("Opera") == -1);
For the page Course 2 it complained about line 15 again:
Found 3 errors in external css files
Found 2 errors in external css files
and again, this is line 15, with the same bit underlined in green that I've made bold here.
On the index page, the problem is on line 36 -
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Wuiz Mendez | Welcome!</title>
<link href="wmstyles.css" rel="stylesheet" type="text/css" />
<style type="text/css">
<!--
body {
font: 100% Verdana, Arial, Helvetica, sans-serif;
and in every case, it  says - Affects: Internet Explorer 6.0; Internet Explorer for Macintosh 5.2
Finally, on the enrolment page, the problem is on line 39:
<title>Wuiz Mendez | Enrolment</title>
<link href="wmstyles.css" rel="stylesheet" type="text/css" />
<style type="text/css">
<!--
body {
Right - now after writing all that down, here, I then went to the css file and checked that too, and sorted out a few oddities. In one place I had put maxi-width on a box size. Which isn't an option, it's either a value or its 'normal'. Anyway, after correcting these issues, e.g. in another place I had put a number only, instead of 12px - when I checked again, Course 1 and 2 were fine, and I think Course 3 was as well but now it isn't. The index and enrolment page also still have the margin on the right.
I think it's external style sheets and not in the css. So am checking but can't see anything invoking padding on the right or margins.
Into the ether I send my quiet desperation and will go off and make some coffee. According to Voltaire, this increases intelligence and God knows I need it.
