It’s working with 1 loop per year. It suits me.
I found the code somewhere else and just add the date condition.
For example for year 2011 :

<?php
				//for each category, show one post
				$cat_args=array(
				  'orderby' => 'name',
				  'order' => 'ASC'
				   );
				$categories=get_categories($cat_args);
				  foreach($categories as $category) {
				    $args=array(
					'showposts' => 1,
					'category__in' => array($category->term_id),
					'caller_get_posts'=>1,
					'year'=>2011
				    );
				    $posts=get_posts($args);
					if ($posts) {
					  echo '<p><a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
					  foreach($posts as $post) {
					    setup_postdata($post); ?>
					    <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
					    <?php
					  } // foreach($posts
					} // if ($posts
				    } // foreach($categories
				?>

Still digging into queries.

I will give a try with multiple queries, 1 per year as it will dramatically simplify the query and make it simple to put my divs containing years.

<div>2014</div>
-article
-article
-article
<div>2013</div>
-article
etc

Ok Chadrew. Thanks for the hint !

I’ll try to unactive each JS to see where is the problem.

I still have no idea how to correct this weird bug.

Any idea ?

Thanks
