I always fly PMDG B738. After got my sim updated to SU14, I got frozen 4 times out of 6 flights. All 4 times occurred on the runway during the takeoff. The other 2 flights were so smooth. They were one short flight (30 mins air time), and the other was 4 hours online using IVAO.
All I could do is to ctrl+alt+del to restart the PC. Looking for a solution here.
