Prepar3d has stopped responding.

[Peter Webber 339]

Good day.

First of all, I have P3D V2.5 with the latest hotfix and running the application on a Windows 8.1 operating system. I use ASN latest Beta and PRO ATC X. I conduct a flight FACT to FALE no problem. When parking at the gate and shutting down the engines with APU running, I leave the PC for a while, and when  I return, P3D has frozen and the PC reports "Application not responding". When I interrogate the fault, I get the message: "P3D.exe stopped interacting with Windows and was closed". Any ideas? This has occurred twice at exactly the same stage of the simulation. Thanks in advance for any input.
