I'm starting to notice this more and more myself with 4.03.
A possibly related problem that again has only started happening in the last week or so is that if I turn off MyFlights for a few moments, usually after having added an aircraft type code to an aircraft in the aircraft table in Database Explorer, when I turn MyFlights back on, the grid populates immediately, but half the time, none of them appear on the map.
I solve this by turning off (real-time) network flights, turning off and on the hardware flights again, and then turning the network back on.
Anyone else seeing this problem?
