Hello Pilots, I have had my CS copy for a time now but every once in a while my 757-200 or 757-300 Starts Turning till it dives into the ocean. The problem only gets solved when i Turn off the autopilot but once i Turn it back on I still get the same Problem. Most of my flights with Captainsim are never finished because of this problem.

My specs
Windows Vista Home SP1
2GB RAM
Nvidia 9500GT
3.16GHZ Duo Core E8500 Intel.

AIRACRAFTS
CS757-200 4.2
CS757-300 4.2

Any tips or help appreciated.
