Thanks Westy for responding. Yes, when I lose calibration, it does show in Windows setup as well. I can simply recalibrate in AH, however, and it is fine (Until it does it again).
I am using a game port on a sound card, Sound Blaster Live with current drivers.
Directx 7.0a also.
I did notice last night that when I lose calibration, I also get sent to zoom mode in whatever view I am in and my engine sound revs, then back to normal. All this happens at 1 time, calibration loss, zoom mode & engine sounds.
