Quicky – top article title displaying incorrectly in IE/Opera

My blog is at https://blog.paulietheboss.com

I don’t want to do much to it, but I have added a calendar style date, and it seems to have knocked the display of the first story out of whack in Internet Explorer, and flush with the top in Opera. All the other ones appear fine, although slightly better in firefox.

Any ideas? I can’t see any reason that the first article header should appear differently from the second, since they’re created with the same code(?)

Here’s the code for that area of my index page;

<div id="content" class="narrowcolumn">

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<div class="post" id="post-<?php the_ID(); ?>">
<div class="date">
<?php the_time('j'); ?>
<span class="month"><?php the_time('M'); ?></span>
<?php the_time('y'); ?>
</div>
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?><span style="margin: 0px 0px 0px 10px;"><img src="https://blog.paulietheboss.com/wp-content/themes/default/images/doggy.png"></span></a></h2>

Cheers to anyone who can help!
