Does not work with external tables

Hello, I have this module working successfully with Drupal node based views.

However, I also use Table wizard http://drupal.org/project/tw to integrate non-drupal tables (ie those containing non-node or non Drupal data) into views - Views Or does not seem to work here .

There are no error messages, but Views Or options are not exposed under filters or arguments for these Views.

Please let me know if you need more info.
