You can set up the "Wallpaper" section of the Weather Watcher Options to display a map as your desktop wallpaper and update it at a set interval. But, did you know you can use this same feature to rotate through multiple maps on each update interval?
To get started, set the desired map interval in dropdown box.
Next, hold down the CTRL key and select each map from the map list by clicking the map name.
Click "OK" to save your changes and prepare to watch your selected maps rotate on your desktop at the set interval.
