Please!! help me!! A/P- wrong!

Hem... So it does this in manual control?Hmm....Strange, the only way i can think of to obtain this is to have a very uncalibrated, poor and juggy joystick, supplying FS with erratic data...Open up the "game controllers" window of the control panel, and have a look at the properties of your joystick: there should be a window with a cross in the middle, it represents the position of your stick; now move it around and see if it is smooth or jumpy.Maybe it's the joystick?But i do not believe it, since it does so also on autopilot...
