 Contextual help never shows unless I echo it in my added filter.

 Excerpt from my plugin:

 add_filter('contextual_help', 'fpw_cat_thumbs_help', 10, 3);

 function fpw_cat_thumbs_help($contextual_help, $screen_id, $screen) {
     global $fpw_cat_thumbs_hook;

     if ($screen_id == $fpw_cat_thumbs_hook) {
         $contextual_help = 'My help goes here...';
     }
     return $contextual_help;
 }

 That does not work!

 function fpw_cat_thumbs_help($contextual_help, $screen_id, $screen) {
     global $fpw_cat_thumbs_hook;

     if ($screen_id == $fpw_cat_thumbs_hook) {

         $contextual_help = 'My help goes here...';

         echo $contextual_help;

     }

     return $contextual_help;

 }

 That works.
