Wordpress DIV tag issue

http://profile.zc923.homeip.net
In Firefox, the links in the post work. In IE, it treats the the links as regular text.
After a bit of tweaking, I found it to be a div tag in the index file of the template.

<div class="entry">

Even If I put a </div> directly following this, the links still do not work. Its not even a css issue. The only way I can get it to work is to remove the code itself.

I swear, when I modified the template, it worked. The only reason I found out of the problem was when a frequent visitor told me the links in the post no longer worked. The code had remained unchanged since then.

Any one have suggestions?

I hate this.

2 seconds after posting, I tried something and it worked.

<?php 
get_header();
?>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="entry">

With the code line in the header was

<div id="main">

I removed the main div from the header, and placed it like this:

<?php 
get_header();
?>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div id="main">
    <div class="entry">

It works now, But pushes the sidepbar all the way to the bottom of the page in both browsers.

Isolation of the problem even further,

<?php 
get_header();
?>
<div id="main">
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

    <div class="entry">

This places the side bar correctly, but links don't work in ie.

EDIT: Ignore everything. Apperantly, IE does not like negative margins. The div tags had nothing to do with the problem. Still, why would IE suddenly stop accepting something it accepted earlier?
