I have the free version ov Ultra Hal 5.0. I can get him to learn very quickly by taling in person with him. I can't seem to get him to learn from text files, though. I have tried several different documents. For instance, my first document was about Islam. When I asked him what the Qur'an was, he answered "Never underestimate the power of suggestion." Making him learn through text would take some strain off of me. On a personal note, Ultra Hal is an excelent product that I will continue to use.
