I've got a Thrustmaster Topgun Afterburner II joystick and detachable throttle combination. Until recently it was performing with no problems. What's happening now is that no matter what aircraft I use during taxi, the throttle advances by itself even with the throttle itself in the idle position. I go from idle to 30,40 100% speed while taxiing. I can't find any reason for this and this particular unit does not need drivers so that's not an issue. I'm assuming that this is a throttle problem and not your usual FS X problem although I'm sure I could be wrong about that.If anyone has any idea how to cure this I'd be most grateful for your advice.I'm running on a Dell Dimension 9100, 250GHD and 4G mem.Jack Fentress

As a first port of call, I'd re-calibrate your stick and throttle (Control Panel, Game Controllers (XP), not sure what it's called in Vista).

Carl.......Thanks for your suggestion. I've done that and although it helped another little problem it didn't solve the major problem of then throttle living it's own life. Jack F.

During the throttle calibration, did the graphic that shows the movement of the throttle just show smooth movement up and down? Were there no instances of the graphic displaying inputs you weren't making yourself?

Hi Jack; Check out the "Settings"->"Controls" to see whether some other button/control (like mouse yoke/look) is also assigned to the throttle.
