HiI've created a topic on CTD Forum (http://forum.avsim.net/topic/357071-fsx-with-pmdg-737ngx-freezing/), but now I guess it's better to ask for assistance here. Since the last time I reinstalled both FSX and 737NGX, FSX has frozen 3 times. And exactly when I was descending or approaching, editing waypoints and setting VRef. It seems to me that FSX freezes when I hit a button on CDU. I bought and downloaded PMDG yesterday. So I guess it covers all hotfixes and SP1b.I'd appreciate any idea on how to find the cause or solution to it.Thank you!
