issue with category pages

The site I’m working on has a page for each category using the following code:

<?php
if (is_page() ) {
$category = get_post_meta($posts[0]->ID, 'misc', true);
}
if ($category) {
  $cat = get_cat_ID($category);
  $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
  $post_per_page = 4; // -1 shows all posts
  $do_not_show_stickies = 1; // 0 to show stickies
  $args=array(
    'category__in' => array($cat),
    'orderby' => 'date',
    'order' => 'DESC',
    'paged' => $paged,
    'posts_per_page' => $post_per_page,
    'caller_get_posts' => $do_not_show_stickies
  );
  $temp = $wp_query;  // assign orginal query to temp variable for later use
  $wp_query = null;
  $wp_query = new WP_Query($args);
  if( have_posts() ) :
        while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<div class="new-wrapper">
<?php the_time('F j, Y'); ?>

     <h3 class="storytitle"><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h3>

    <div class="storycontent">
        <?php the_content(__('(more...)')); ?>
    </div>

</div>
    <?php endwhile; ?>
    <div class="navigation">
      <div class="alignleft"><?php next_posts_link('? Older Entries') ?></div>
      <div class="alignright"><?php previous_posts_link('Newer Entries ?') ?></div>
    </div>
  <?php else : ?>

        <h2 class="center">Not Found</h2>
        <p class="center">Sorry, but you are looking for something that isn't here.</p>
        <?php get_search_form(); ?>
        </div>

    <?php endif; 

    $wp_query = $temp;  //reset back to original query

}  // if ($category)
?>

However the ‘more’ part doesnt work and the writing after the ‘more’ just spills out onto the page.

However on my home page where I use the standard coding for WP the ‘more’ works fine. The posts are displayed in a grid with a limited space per post so the ‘more’ bit is quite important!

But as far as I can see the ‘more’ coding is identical on both parts using:

<div class="storycontent">
        <?php the_content(__('(more...)')); ?>
    </div>

Can someone please help me to rectify this issue? I’ve been racking my brain for days and I cant get it to work.

Thanks!
