Hello:

I bought this bird a couple of weeks ago, so I believe I have the last version installed. Despite that, I am facing the same troubles reported on this post more than a year ago!!!
In my case CDU entries can just be done very slowly - as reported here - and even slowly, my FSX is crashing during CDU entries whenever I am playing on Multplayer mode. So far, I did not have any crash in Free Flight Mode.
I really apreciate a fast reply from CS about this issue, since I just use FSX in Multiplayer sessions and I don't intend to change that.
Thank you.
