This revision provides better compatibility with plugins (doesn’t rely on POST data), and only updates custom taxonomies, not built-in ones.

add_action('save_post', 'jr_select_parent_terms', 10, 2); // automatically select parent terms
function jr_select_parent_terms($post_id, $post) {
	if( $post->post_type == 'revision' ) return;
	$taxonomies = get_taxonomies(array('_builtin' => false));
	foreach ($taxonomies as $taxonomy ) {
		$terms = wp_get_object_terms($post->ID, $taxonomy);
			foreach ($terms as $term) {
				$parenttags = get_ancestors($term->term_id,$taxonomy);
				wp_set_object_terms( $post->ID, $parenttags, $taxonomy, true );
		}
	}
}

I have improved the code to work on pages with multiple loops:

<?php $sticky=get_option(‘sticky_posts’); $randomStickyNo=0; $randomStickyNo=(rand()%(count($sticky))); $postno = $sticky[($randomStickyNo)]; $temp = $wp_query; $wp_query = null; $wp_query = new WP_Query(); $wp_query->query(‘p=’ . $postno); ?>

I was getting very strange behavior due to the multiple loops. Some browsers (Chrome, Firefox) would display the correct post, and IE6, IE7, Safari would return as “not found”.
