LOL. Seem like fairly wise words. I sympathise with you then if you're trying to get MS FlightSim to emulate something a bit more realistic. I have a friend who pretty much has all the possible MS FlightSim attachments going, and he has it working OK, but he once offered to sell me all his gear because he got fed up with niggles and crashes and so on.
As a simple instrument training program with simple equipment, its pretty good and worth what you pay for it. I believe the 'Ice Pilots' were using it to practise DC-3 IFR flying, but I may be mistaken on that point.
