mvsetup

I'm new to this site,and I will try to keep it brief.i work with arch backgrounds and sometimes I have to rotate the viewport to max the space depending on the shape of the building.Whenever I do this my drafting settings become DE activated,as well as a DE activation of the nonverbal/verbal setting in the selections tab,and I always have to reset/activate this,but it only happnes when I use mvsetup to rotate the viewport.Any clue will be greatly appreciated,thank you...Al
