With kind permission of its modifier, Storyr, from an independent
Weatherpanel forum, I am providing a replacement weatherpanel.dll that should fix the moonphase calculation problem. As I mentioned in my post above, Storyr provides instructions on how to do this. They are as follows:
Installation instructions:
1. On your device, go to Start -> Settings -> Personal -> Today. Open the Items tab and uncheck WeatherPanel.
2. Dock your device and browse to \Program Files\MarsWare\WeatherPanel.
3. Make a copy of WeatherPanel.dll (or rename it), then unzip and copy the new WeatherPanel.dll to the same location.
4. Go back to your Today settings (as in #1) and recheck WeatherPanel.
NOTE: You may get a message about running a program from an unknown source. Be sure to OK this (it's a one time deal).
Thanks to Storyr and his group for solving this!:approve:
