I'm going to be honest man, this is silly. I've been playing arma with trackIR for years and never had this problem. Add in a deadzone so your view isnt going bat shit crazy, sorted.
I had BAF, and then I reinstalled arma2 again and when I went to instal baf again, norton decided to delete it for me. Now I can't download BAF without re-buying it. Can anyone point me to a download link or something please?
