yep it seems to be there. this is the code from lines 73-101. also when there is no item in the cart the side columns touch the nav bar (no gap). but when you add an item to the cart, it creates a small gap between the side columns and the nav bar... maybe that has something to do with it???

Code:
 
 /**
  * prepares and displays header output
  *
  */
  if (CUSTOMERS_APPROVAL_AUTHORIZATION == 1 && CUSTOMERS_AUTHORIZATION_HEADER_OFF == 'true' and ($_SESSION['customers_authorization'] != 0 or $_SESSION['customer_id'] == '')) {
    $flag_disable_header = true;
  }
  require($template->get_template_dir('tpl_header.php',DIR_WS_TEMPLATE, $current_page_base,'common'). '/tpl_header.php');?>
  <div id="contentMainWrapper">
    <div id="contentMainWrapperb">
      <div class="outer">
        <div class="inner">
          <div class="float-wrap">
            <div id="content">
              <div class="contentWrap">
     <?php
  // Display all header alerts via messageStack:
  if ($messageStack->size('header') > 0) {
    echo $messageStack->output('header');
  }
  if (isset($_GET['error_message']) && zen_not_null($_GET['error_message'])) {
  echo htmlspecialchars(urldecode($_GET['error_message']));
  }
  if (isset($_GET['info_message']) && zen_not_null($_GET['info_message'])) {
   echo htmlspecialchars($_GET['info_message']);
} else {
}
?>
thanks!
