I just opened up my drawing which has more than 12 hours of design time into it and now every time I try to use the 3dOrbit commands ... any of them ACAD overrides the command to the 'walk and fly' mode. I can right click and choose one of the orbit modes but that will only hold for a single position change then ACAD set everything back into walk or fly or pan, depending on what I just tried.
Any clues on what could have happened?
