If I do a soft reboot, it comes back but the next time I put it into the dock...no weather.
So far the only weather one that I can find to start each time you reboot is WeatherBug, you may want to try that one.
Yeah, mine goes on and off too...I think it's an Accuweather issue. I find it hard to get the location changed, too.
It's really bumming me out. The weather was one of the reasons why I wanted that dock.
