Running AirNav on my Laptop using wifi everything works fine for days or even weeks. Then, for no apparent reason, when I boot up Airnav the screen display reverts to the initial settings, and all my ALERTS data is wiped out. I have to clear vertical tracking, re-set interface, etc. Very boring. If this is the result of Windows Updating, or any other computer process, how can I preserve my Alerts data? Some settings are retained, home station data, map settings, etc.
Apologies if this topic has been raised before.
Thanks
Ian
