I'm curious about something.When you're flying online in FS 2004, and warnings pop up saying other virtual aircraft are not compatible, does that indicate that they aren't in theSB CSL directory, or does it mean they're flying in another flightsim such as X-Plane?Slugger

Nope its just something with FS2004. You should get a options to display this aircraft. Or something like that, select yes or ok then FS will make a note of this and never ask you about that aircraft type again. The SBRelay readme file has a list of aircraft you can add to your FS9.cfg file that will stop most of these messages

Dave,Thanks for the quick reply.I look forward to trying your suggestion.Slugger
