This was introduced on my system with 1.8.3 but is not fixed with 1.9.3 now:
The history of last loaded airports does not work and all my settings I make to the filters of the world map are also not saved.
I have still the airports in my history list from flights before 1.8.3.
1.8.3 was also the point, where my logbook ended to work and stopped to record anything.
So, probably there’s a file or folder I can delete or reset?
Will report that to zendesk now
