third column beyond main wrapper, product description moving beyond third column

Hello,

If you go here using Internet Explorer you will notice that the third column is really messed up. It appears well beyond the main wrapper. If you shrink or expand the browser you will see that the third column is actually in a fixed width.

What is causing this? I cannot seem to find any real problem with the stylesheet that is used.

You can find this problem occur in most of the product pages.

Here is another example.

I have searched with no answer so far as to a solution to this.

Regards,

Part of this is this in the css

#mainWrapper {
	background-color: #ffffff;
	text-align: left;
	width: 1135px;
	vertical-align: top;
	}

More importantly, in the page you provided have the center description in a battery of defined tables that do not fit the space.....Get rid of the tables or reconstruct them to auto span the available space
