Calling WP_Query does return a Post, but not the Tags

Hello,

My index.php looks like this (irrelevant HTML skipped):

$myPosts = new WP_Query('category_name=xxxxxx&showposts=3&order=DESC');
$myPosts->the_post();
print "<h1>" . get_the_title() . "</h1>";
print get_the_tags('<p class="tags"><strong>Tags: </strong>', ' | ', '</p>');

My problem is that the title is returned, but the tags are not.

I have read the file query.php but cannot find a clue where to look for a solution. I hope this is not too much a newbie question.

Thanks for your help.
Regards,
Bert
