Recently, when I try to change the NAV source from vor1 to another source ( fms ), system crashs to desktop.I have reloaded the TBM files from original and deleted the history file w/ no success.Is there another FLYII file that communictes w/ the TBM nav selection that might be corrupt?

Indeed, on windows2000 the push of nav source can cause a crash to desktop.Regards,Frank

Kline:As Frank said, I think that's a known bug. I may be wrong, but I think it's even mentioned in the documentation that comes with the TBM.Regards,Alejandro AmigorenaCheshire, CTAthlon XP 1800ABIT KR7A-RAID768Mb RAMGeForce 3 64MBSB Audigy GamerCH Flight Yoke USBCH Pro Pedals USB
