Hi Markoz,
Thanks for the fast reply!  I've been flying the 727-100 for months with no problem.  I just downloaded and installed the 727-200 expansion today, so if I'm reading the CS writeup correctly it should have 2.3 (which was dated 12/25/2009) incorporated into it.  I tried the 2-D autopilot control which I've always used with the -100 (I open it and then undock it and move it to a second monitor) but as reported the aileron and elevator paddels would not engage, nor could I move the disk at all from manual to the other settings. The altitude hold switch also would not operate. I forgot to mention in the earlier posting that I have FSX SP2 but not acceleration and the latest FSUIPC. My OS is Windows XP with the latest upgrades.
Thanks for your suggestions, and I hope you can continue to help.
