[support] Problem with thickbox and drupal5

Hello, I'm trying to use thickbox "http://drupal.org/project/thickbox" and Drupal 5. The result of my problem should be see at "http://drupal5.paupe.name/?q=image/tid/2". I don't know whereis the problem but i tested all *.js *.css files from the module and jquery.js from Drupal, and it works fine wich own html page. It's possible that's a drupal.js problem ?
