When flying the new PMDG 737nx and using ASE and weather program my auto pilot keeps disconnecting and plane rolls violently. The wind speed and direction constantly changes 23-30 degrees. I keep getting crazy s turns and when plane tries to correct itself pass 30 degrees back, autopilot kicks off and plane rolls out of control.If I switch back to AS6.5, all goes well, no more s turns and volent wind changes. This only occurs with this particular aircraft. I tried with PSS 757 and Feelthere busus and they work ok with ASE. Not sure if this has been reported, please advise solution.Thanks in advance for help.Bill M

Please read manual that comes along with ASE. S-Turns were described there together with advice as to what to do in order to avoid it.NGX works perfectly with ASE.
