Page Won't Center in IE, page will not center in Internet Explorer Options

[BleuBayou]

Greetings,

I have a feeling this is a CSS issue and not an IE specific issue but anyway,

Open Firefox and IE and go to http://www.bleubayou.net/locator/index.php

In Firefox, the page centers the way it should, click any button on the navigation and it will be centered on every page. Now look at it in IE and then click any button in the nav. Only the Store Locator page is not centering. Any ideas on how I can fix this?

This is a PHP page that calls on a template file. The template file has two CSS files linked to it. It would seem to me that that one of the CSS's needs a style for:

margin-left: auto;
margin-right: auto;

I added this to the body style but so far no luck. Please help. Perhaps something that the index.php page is pulling it is causing this? What do you think?
