customised loop and categories with 2.0

Hi,

I have just upgraded to WP2.0 *almost* seamlessly and am just trying to sort out a few glitches.

I was previously using categories and then customised loops to give a blog page with “notes” down the lefthand side and “articles” in the main content area. (where notes and articles are different category names).

The loops looked like this:

<?php query_posts('category_name=article&showposts=7'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

<!-- do stuff ... -->

<?php endwhile; endif; ?>

After the upgrade this format resulted in no posts being displayed.

I have changed the first line to

<?php query_posts('category=1&showposts=7'); ?>


(ie I am using the category id number rather than the name). This now displays the last 7 posts from *all* categories.

Do I need to change the way I am querying the posts?
I would like to get back to displaying only the posts within a particular category.
