After installing vers. 1.1, I experienced problems with the cockpit with blank squares momentarily flashing, and lines dark lines running through the cockpit. I remembered that after installing vers. 1.1, FSX did not ask me if the CS707 dll's were trusted.  So I uninstalled vers. 1.1, opened up my FSX.cfg file, and erased all the entries under the "trusted" heading.  When FSX restarted, it asked me if the CS dll's were trusted, I said yes, and the cockpit appeared with no problems.  I hope someone will find this useful.  Mike Gutierrez
