Hi everyone,
Sorry to bring back this issue! I just purchased the IXEG 737 and have the same issue as mentioned above. However, I don't use an external hard drive. I have X-Plane 11 installed on a Western Digital WD10 Blue 7200RPM so the external hard drive isn't an issue. Moreover, I don't have any anti-virus or Windows Defender active.
I've been trying this flight for the past two nights where I take off from KBOS and fly into KPHL and mid-flight, when I go and select my STAR as well as approach, the sim starts freezing every other second. The more I use the FMS, the more the freeze. I don't have this problem otherwise, that is, if I don't go in the FMS and play with it mid-flight.
