I identified the ACE problem and FIXED. Every time,  I try to make  a   clean uninstall / reinstalling ,I found old October 15th 707 and  cfg   file was still reamaing in FSX Sim Objects / airplanes folder. Therefore  corrupted ACE was remaining unchanged. How it is possible, I dont know.

Manually I deleted October 15 installation from FSX Sim Objects /Airplane folder and Today Nov 1,2010 installed fresh 707 from Captain Sim side.IN Sim Obcets/Airplane date turned toNoc 1, 2010 And  new ACE saved  the" Flight Deck Only"
:D :D :D

Now, only problem still remaining is "Flashing". May be  some one will get  lucky like me and will solve this problem also. ;D ;D
