Two dialogs are displayed: (1) Cannot load window system persistent data, user directory content is broken... (2) Cannot load even default layout, using internally predefined configuration. After these dialogs are closed, I can display an unhandled exception. Unfortunately, copy does not work, so I will attach a screen shot. <img width="1079" alt="screen shot 2017-04-11 at 5 31 19 pm" src="https://cloud.githubusercontent.com/assets/6628505/24936280/bde99b60-1edc-11e7-9099-3e0edec02467.png">
