After doing a computer reformat, I've just reinstalled all my addons and found that my 727 is not operational.  Some of the problems are - Yoke is missing, Window is open and can't be closed (sounds like its closing, but does'n't), Can't click on any of the overhead buttons and cannot move any of the control surfaces.  Oh my.  I've read that someone else had this problem and fixed it with a FSX reinstall, this is not going to work for me as I've just reinstalled FSX and the many, many addons I have.  Any ideas what has happened here?
