DataShuttle should handle not-logged-in state gracefully
I installed the client, and then tried to log in. It said I could use my google login, which I presume meant that Google single-signin would work, but the app then proceeded to ask me for my google username and password. In general, I don't give a desktop application my google account password, so I decided not to login. I wanted to quit the app, but there was no way to do that! The red dot in the upper left hand corner was disabled, and the Quit selection in the FireCloud DataShuttle pull down was not responsive. Ended up having to force quit.
