In FSX flaps only move slightly and then go back to up. Gear retracts OK but red lights remain on. Gear handle can be moved to Off but when selected down gear will not extend and red lights remain on. Also on some 737s, not all, the anti-skid selectors are OFF and cannot be selected ON. Can somebody please help me with these problems, I have tried everything I can think of with no success. This is a fabulous aircraft but if I can't get it working I won't be able to enjoy it.
