Pagination showing same posts on all pages

When I click on page 2, it shows the same posts that are on page 1. I have read 20 different threads about this problem, but can’t find a solution that works. This is my code:

<?php global $paged;

$bcat = get_option('of_blog_category');
$bcatid = get_cat_id($bcat);

query_posts(array(
'cat'=>$bcatid,
'posts_per_page' => 5,
'paged' => $paged
)); ?>
