nested loop leading to an infinite loop

hey everyone…

I have an infinite loop and I can’t find why… I’m sure it’s staring me in the face but here we go….

<?php if (have_posts()) : ?>

		<div id="categorytitle">
		<?php the_title(); ?>
		</div>

		<?php get_sidebar(); ?>

		<?php while (have_posts()) : the_post(); ?>

			<div id="contents" class="twocolumn">

				<?php the_content(); ?>
<?php include (TEMPLATEPATH . "/includes/flipbook.php"); ?>
			</div>

		<?php endwhile; ?>

	<?php endif; ?>

the include flipbook.php file is as follows…

<h2>Flipbook</h2>

<p>
	<img id="largeImg" src="images/img1-lg.jpg" alt="Large image" />
	<div id="largeText">
		<h2></h2>
		<p></p>
		<a></a>

	</div>

</p>
	<!-- element with overflow applied -->
<div id="btnleft"></div><div id="panel">
    <!-- the element that will be scrolled during the effect -->

<p class="thumbs">

	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
		<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><img src="<?php $values = get_post_custom_values("Image"); echo $values[0]; ?>" title="<?php the_title(); ?>" caption="<?php the_excerpt(); ?>" alt="<?php the_permalink(); ?>"/></a>

<?php endwhile; ?>
<?php endif; ?>	

</p>

</div>
<div id="btnright"></div>
<div class="clear"></div>
