Sometimes, FSX freezes exactly 10 meters altitude before landing.It seems that happens only when I start from a saved flight selected directly after I open FSX (738 is on cruise or approach). It can happen on any airport.To solve the problem (no freeze), I start FSX, select the 738, go to the departure airport. Only after that (after parameters have been initialised on ground), I select the saved plan.Sorry for my poor english.My name is Edouard.
