Hi Nigel
Point 1 - you can set the panes using the Tools Menu...Interface...Left/Right option, and then drag the divider to the location you want. When it's all how you want it, use Window...Record Desktop so that it will remember your layout.
Point 2 - I don't know how you set your home location in the first place, but the my preferred method is to use Google Earth to pipoint your location, making sure that you have used Tools...Options..Show Lat/Long and chosen Decimal Degrees.
Enter the coordinates into RadarBox, making sure that, for Liverpool, there's a minus sign in front of the Longitude.
Hope that helps.
