Welcome to 2017!
I am having intermittent problems as other have stated: sWeather goes "blank" at times, reporting NO DATA for all locations (even Codyville!). I have found that a few refresh attempts restores the data. As I have no working knowledge of the Yahoo API, I am wondering if the call out (polling) to Yahoo is persistent enough to insure connection. Hey, it's only a weather program (and a fine one too), but it's just a thought.
Many thanks for the effort.
