I was flying the B1900D today on autopilot & about 10 min. into the flight the engines just cut back to idle. When attempting to advance the throttle it would snap back to idle. I have had it since it came out & has always flown OK until today. I restarted FS2004 & then attempted to move the throttle forward to full to take off. The RPMs would pick up for a few seconds & the throttle would then snap back to idle. Am really puzzled by this as it has always flown well up to today.Any ideas for a fix for this?Thanks,Bob Anderson

Any chance you've got more than one joystick/gamepad plugged into your computer? You may have multiple axes defined controlling throttle?
