[support] statistics not working on some node types

Hi there, Do you know if the core statistics module allow some node content types to be excluded from being logged ? Since a few days, one of my CCK node type doesn't seem to execute statistics_exit() anymore, and I just can't figure out why ! I use a custom theme using a node-mycck_theme_name.tpl.php file, and everything works fine except that stats are not recorded anymore. I search in all administration pages, google & drupal search, but couldn't find where this could come from... :-( _Any_ ideas welcome... Thanks, Pierre-Yves
