I and another forum subscriber am wondering where "TrafficInfo.DLL 9.0" came from?I think if you check your FS9 Modules folder you might find "TrafficInfo.DLL 9.0". The FS 9 CD index doesn't show it nor do I see it in Disc 2 MSGAME3.CAB .If it came with the 9.1 patch it would seem it should also have the version number 9.1 instead of 9.0 .We're just wondering.

TrafficInfo.dll is supplied by Microsoft as part of the "Panels and Gauges SDK" (Software Development Kit):1. TrafficInfo.dll. This DLL should be installed to Flight Simulator

Thanks Bill !......
