Hello,
I have got the exactly same problem... and I have tried everything (total reinstall - FSuipc on/off - command key only - with or without joystick....) I have contacted BBS team and they told me that there are ok to refund me as they can't reproduced the bug on their computer.
I have said that I will wait for the 0.85 version, cause the bug was not there at the 0.66 version so i guess this is inherent the the current version. They said to me on the 21st june that the update will take weeks rather than months, so I hope it will come prior the end of august.
I have searched over the internet for hours and hours without success, We'll have to wait for the next version, and hoping that the problem will be solved and if it's not, wait for the Aerosoft 330 and get a refund...
But if there is a solution out there I would be very glad to hear it...
Sorry that doesn't help
