Hi. Im new to the AVSIM forums and am here seeking help with a problem I've been having. I just got a new, rather nice system that runs Windows 7 64 bit on an AMD FX 4130 Quad Core @3.80 GHz, 8 GB of RAM, with a Geforce GT720 with FSX SP2. The issue I've been seeing has been happening with about half my flights. I'll get about halfway through or nearing the end, and out of nowhere FSX just stops. It seems to happen at random and is majorly frustrating. I have to tab out and close the process to close FSX. I don't know if there is an easy fix to this, but I have tried the UIAutomationcore dll and running in compatability mode to no avail. It also runs as an admin. I run RealFsWx lite alongside. Any help is much appreciated.
