Okay, if I click on a flight on the map, it circles the aircraft and retains that until I move the mouse over another aircraft.
If I select the aircraft on the MyFlights list it also retains the hold on the aircraft, list will still move around but it retains the selected aircraft.
The main thing that would give you problems is moving the mouse around the map, as when the mouse goes over a aircraft it automatically selects that aircraft on the map and selects it on the My Flights list.
