EarthDesk is working, but its showing daylight in the wrong place. Why?
The most likely problem is that the Home Location is not set correctly. Open the EarthDesk Preferences window and click on the “Atlas and Home Location” tab. In the city list on the left side, find the city you are in and drag it to the Home Location box at the top. Note that you must click and drag on the actual text and not in the blank space between the city and country names.
