Hello, I have buy today at Simmarket the 757 and I make a first fly before to read this forum. I discovered the 4.2 version, so , I get it and install it... I also have had the problem with the autopilot, and couldn't take back manual control during approach. Reading this topic : http://www.captainsim.org/yabb2/YaBB.pl?num=1227900846/15#15   I have make much more simple : I had saved old versions of FSUIPC.dll ... I simply have replace FSUIPC 4.4 with the 4.3 and the first tests seems to show that the problem is solved. I will make some other flights tomorrow and tell you if the problem have not be back. It is very easy to change FSUIPC without desinstalling and reinstalling the 757... But it mean that you have saved old FSUIPC versions...

I have the same problem. I do the the same as you, I use the old FSUIPC to replace the 4.4 ver which installed by CS757. And the sometimes the same problem will happened. I am very sad.
