Theming main menu with block--menu.tpl.php not working My template file block--menu.tpl.php is not catching my main menu block. It works for custom menus. Am I missing something on this? I don't have any other specific block overrides.

I'm running Drupal v7.10
main-menu comes from system module, so it should be block--system--main-menu.tpl.php 

Cheers
