We are currently on V7.1 without any SP version. We are facing a problem wherein on a project plan even though I do not mention a resoruce as a project resource either at the tasks or stake holders level the person is still able to book time to it. I have checked the project type seetings also, In the cost and effort tab it s set as "All Resources" - who can view the project (including stake holders) can book time to it. In the Project Security tab I have allowed on the Project particpants to be able to view the project. Is there a bug in this version of 7.1 or am i missing on something here.
