Permissions not apparrent?

HI,
Hope you are still supporting on this module as it answers a real need for me. I've been working at a rather complex review and distribution workflow for a site and just this evening came across the Taxonomy Access module, which will help loads in restricting access based of workflow state reflected as a taxonomy term.

So, after installing your module I set one vocabulary to be view only for all user roles. But when I edit or create content in a content type that includes that vocabulary as a normal user the control is still editable. SO I switched all the roles to not show, and still they come up editable.

As well as node access I am using node access, if that has an affect on the function of your module.

Any thoughts why your module would have no effect?
