Yesterday I was dragging a fly by control point and my mouse pointer came off the point. My terrain suddenly disappeared from view. I put my pointer in the scene view and hit F and got the terrain to reappear, but it is in the distance and the perspective is screwed up. I double clicked Human Height, but when it zoomed in I got a bizarre image. My W,S,A, and D functions are not working properly and notice the X,Y,Z perspective is not appearing in the upper right hand corner of my scene view. Anyone have any idea how I can get this back in order?
