[sydney68 4]

Hi all

I seem to be having a problem with active sky next.i purchased the airbus 320/321 from aerosoft.when I fly from any airport in the UK it's OK then about 10 min in to the flight the airbus started to gain speed and also started to increase in altitude even thought autopilot was on.so what I did was closes the sim down and then restarted the sim but not with active sky weather engine instead with the rex weather engine turned back on so only rex and no active sky did the same and no problems from rex anybody had the same problemm
