How to have start page default to a single category?

Ok i solved this (sort of) by including this code on the index.php file

<?php if (is_front_page()) {
	query_posts('cat=1');
   } ?>
   <?php if (have_posts()) : ?>
  <?php while (have_posts()) : the_post(); ?>

However this is causing problems with the Infinite Scroll plugin. Now when I reach the bottom of the page, it reloads the same articles. It keeps looping and does not load the next page of articles.

*The same thing happens when I disable this plugin and use normal pagination. The “previous articles” link returns the same set of articles, not the next set.

Is there another way of achieving this that would not mess up the pagination?

Thanks!!

(wp_query() and query_posts() are using the same parameters)

Thanks but I was able to solve it with this plugin
