The connection problem has resolved itself now, but I'll let you know what happens the next time I encounter it. (No, sorry, I'm not going to unplug my internet router just for the sake of this. )

I did, however, download Auto Pilot and set the clock to the start-up app. Hopefully this will take care of the problem.

I wanted to add, though, that every time I lose connection to OUYA's servers I stupidly try to go to the "Account" page, which is where I get stuck. I can still play games (so long as I don't turn the console off) if I don't go there... but I always go there, and that always messes everything up until OUYA's servers become accessible again. Will I ever learn?
