I'm running an old "steam driven" computer. Clock speed 350MHz, 65536KB RAM, Win 98. I'm using a Hitec Laser 6 RC transmitter via a USB port. All used to run well until recently a local guy replaced the power supply (as my PC was freezing/rebooting intermitantly) since then I cannot run FMS properly. It will load, all the controlls run normally, but at one frame per second. That's too slow even for an old guy like me. Can anybody help please!!!! My wife flies model aircraft to, and is having withdrawl synptoms not being able to practice with FMS.
