I don't know if it is a beta problem or a resource problem, but many of the links in the book are not working. For instance, in the article Romans 4:1-22 Abraham made righteous by faith, many of the links show the tool tip only, indicating the reference, and not the pop up containing the information. In the first sentence, only proselyte and Gentile have the pop up. All of the other words just give a tool tip for the Pocket Dictionary of Apologetics and Philosophy of Religion.
