Disappointed by the product. Yet I have long used the Dragon software. Many crash. Slowdowns. Incomprehensible messages. The Dragon technical service has no real solution, if not you have to book all the computer resources to the software, by closing all windows, etc .. It becomes very complicated, while Dragon 10 requires nothing of the kind. I said that my computers are recent for one and the other nine with beautiful patterns. I uninstalled version 11.5 for returning to version 10. A real waste!
