Anyone using Windows 7 yet? I am considering the purchase of a new computer for upgrading my sim, and all are now using Windows 7 as the operating system. My concern is already used products, GoFlight MCP, FSXpand, FS2 Phidgets, and not to mention FSX itself working properly, so anyone who is using Windows 7 please, PLEASE let me know if you have experienced any problems. As always "MANY THANK YOUS" in advance. Dave
