Yep.. it'll bite! I don't know Norton (ugh) but someone may be able to tell you how to allow Norton to 'pass" the Duenna connect and not crash it.
Also, if you have to use the Flight Analysis screen try to expand the range to show the whole flight, not just the landing. The RTW committee says:
d) Duenna Errors.
In the case of an error in the RTW-Duenna software, pilots may take a screenshot of Flight Simulator's Flight Analysis window upon their arrival. This screenshot must show the entirety of the flight route, to the best capability of the program. Pilots should also make public any other evidence they may have in support of the authenticity of their flight. The Executive Committee will examine all evidence and come to a decision as to whether to certify or invalidate the leg while the team continues to advance its baton around the world.
