Members - Leaving All Posts Unprotected as defauls


I have installed Members (full version). I want to protect my pages (which I have done, simple enuf) but I want to leave ALL posts, past and future open to all users. I have tried to add all the Categories to the Allows, but still wont let visitors (free users) see the posts detail. Seems simple but cant seem to do it.

Please help. To recap, I dont want to protect any posts by default.
