The documentation of components is pitiful - if a product has a field that can be entered somewhere in the documentation there should be some reference to what that field means and what could be entered. The specific I am looking at is the CaptionField in the data box properties. I cannot find any reference to it in the documentation. This lack of documentation I have also struggled with in the security comonents. It would save a whole load of time and trouble if there was a comprehensive reference manul.
