The author responded quickly to my inquiry and I found out that I can't include Wx in my "Login" items as it won't run well. Now when I start it up manually some of the time it won't provide a forecast. Tonight for example I'm getting "Wx Error: the NDFD server did not return valid point forecast data: Requested 7 days but received 0 days".

Wx is very pretty but I want something that just works all the time. I've used WeatherDock for about a year and while it's not quite as pretty as Wx, it is very reliable.
