I have had to reinstall BT 7th edition due to a reformatting of my hard drive. Unfortunately, I have the ghost plane problem but unchecking the DX10 preview option does not solve the problem as it did for HansRoaming. Oddly, unchecking DX10 preview results in my display inside the program going black. I did not have any problems at all with the sim when I loaded originally on the computer a two years ago or so. The aircraft checks out fine otherwise. My OS is Windows 7 with an AMD quad 4 processor handling the graphics. Has anyone had this problem?
