Make sticky posts behave as normal using caller_get_posts=1 isn’t working

I’m making a specific single.php template. It’s using a jQuery slider to slide from one post to the next. In order to show the right post first, I have to use 2 loops – one to call the first single post, and then another loop to call all the other posts in the category.

This I do like this (might be a bit mucky, I’m no PHP guru)

<ul id="tour-items">
				<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
				<li>
					<h2><?php the_title(); ?></h2>
					<?php the_content(); ?>
				</li>
				<?php endwhile; endif; ?>
				<?php $briefingsposts = new WP_Query(array(
					'caller_get_posts' => 1,
					'category_name' => Briefings,
					'offset' => 1
					)); ?>
				<?php while ($briefingsposts->have_posts()) : $briefingsposts->the_post(); ?>
				<li>
					<h2><?php the_title(); ?></h2>
					<?php the_content(); ?>
				</li>
				<?php endwhile; ?>
			</ul>

However, if the first post is a sticky post, it’s repeating in the category loop despite the 'offset' => 1 which I assume is because it’s doing it’s sticky behaviour and sticking itself to the top.

I’ve tried using 'caller_get_posts' => 1 in the array but it doesn’t seem to make any difference at all. I dont want to exclude sticky posts, just make them behave as normal. Is there a way that might work within my queries?

Thanks,
