Custom Post Type and Category.php

Ok, been at this now since 9pm last night!! I created a custom post type called ‘scrapbooks’. Added the default WP category to this post type using:

<?php
add_action( 'init', 'wpse6098_init', 100 ); // 100 so the post type has been registered
function wpse6098_init()
{
    register_taxonomy_for_object_type( 'category', 'scrapbooks' );
}
?>

Anyway, that works great, displays cats, etc etc. The problem comes when Iclick on a cat to view all posts in that cat, it just displays EVERY post in the custom post type. Now I have tried everything I can think of to fix this, but no joy.

I even tried custom category templates and that didnt work, so am back to using the standard category.php (it isn’t called anywhere else) and that is

<?php get_header(); ?>

<div class="page-overlay">
<div id="page-wrapper"><div class="fake-close"><a title="Pop-up Books from Sussex Paper Engineer" href="https://www.corinaandco.com"><img src="https://www.corinaandco.com/wp-content/themes/candco/img/close.png" alt="Close" /></a></div>
<div id="diary-page-wrapper">

<?php query_posts('post_type=scrapbooks'); while (have_posts()) : the_post(); ?>

Really getting tired of this now, seems like the last hurdle lol.
