Thanks for the fast response. Since my system is pretty heavily "taxed" when running MSFS (GPU is 100% utilized and CPU is 60-80% utilized), I don't have any add-ons except other aircraft. As a test, I removed all add-ons and cleaned up MFSF by deleting all aircraft that I don't use. Once that was done, MSFS would work without shutting down even when using SkyElite so it does indeed appear that it was some sort of incompatibility. I love the detailed maps available in SkyElite. Unfortunately, having SkyElite running in the background is now causing MSFS to run at slower framerates which detracts from the experience so I removed SkyElite from my system and I don't plan to use it even though I just bought it. I'm sure it's a great add-on for faster PCs, but not for my machine. Thanks again.
