I was over at the neighbor's again this evening, this time it managed to get set into Airplane Mode and wouldn't pay attention to the WiFi. It took several tries to finally get it to return to using the WiFi in her house.

She asked if I've put Windows 10 in my computer yet (I installed hers a week ago - she wanted it sooner, but we waited so Microsoft could push out a major update.) "No, I'll wait till I've worked out the bugs on your computer first."

My friend, the guinea pig. :)
