Hello,I have the A340 CD Version, using FS9.1 under WinXP SP2. When flying the aircraft, FS freezes and the "buffer overrun" error message is displayed, causing FS to be exited.I have looked for similar problems in the forum but it seems that this problem has occured to other people only when they were inputing flight plans into the MCDU. It is not the case for me : the problem occurs in flight, while I am not doing anything on the panel.Could you help me with this issue ?Thank you,Olivier
