Well I really wanted this 707 and downloaded the demo version and I also have the black line in the cockpit. I am afraid to buy the full version if, as I am learning here, they have not fixed it yet.

My computer is not the problem. I7 at 4.4, Three Gtx 980's in SLI at 4 ram each. Nothing gives me a problem graphically in FSX except the 707. So fix it so I can give you money,  ok!
