I'm actually not suffered by freezing frequently, but had encountered about 3-4 times.Yesterday I flew LFPG > EGLL and successfully arrived to ramp. Outside was rainy.Three external sources set and shutdown engines, it's perfectly cold & dark status with Ext Pwr on.After a few minutes I tried build a new route for another flight, then I felt 'it's freezed'.. < Symptoms > - rising/lowering Yoke / MCP switches works fine ant A/T lights on and off.-2D FMC only shows it's initial page and there is no grey-backgrounded FMC. (ext pwr connected) Screen doesn't change at all when I click buttons.-3D FMC is completely frozen but when I click buttons, page shown only with 2D FMC. I didn't look close when I encountered freeze, so have no idea this is same as usual freezes bofore hotfix..After hotfix, in early phase of flight, sometimes I feel some bump(stutter) when I'm climbing after takeoff.It feels like something is forcing the frozen panels to unlock again and made it back again.. (just my feeling) Anyway even with early issues, wanna thank you for this beautiful bird.

Are you by any chance living at the North Pole ?? lol.
