Thank-you! I hadn't installed the update because it wouldn't let me. I've since re-installed X-plane and updated it and now have X737! Would you recommend any specific downloads to improve performance? Not sure if its my desktop, it meets the minimum spec but keeps freezing, the mouse pointer goes static.
