I have started getting an fmcvector.gau fault which causes FS2K to crash. It may do this several times per flight, making it unusable. I have updated the video drivers, checked the wilcopub.com FAQ section (& so I make sure the LT OVHD is off during the day). It appears to be random? Can anyone help???

Not sure if you were implying so, but typically that problem with the light only occurs during the day-to-night transition, i.e. when the sky is getting darker in FS. You have the light off then too?Ryan

I *think* this was addressed in the FS2K2 patch. But I also recall an issue with having the panel lights ON when FS transitioned from day to night. If memory serves, as long as you leave the lights OFF during the day and only turn them on when it's night, you avoid this bug.
