It's weird..  This isn't the first file I have had this happen with.  It gets even weirder...  Ince it goes upside down, if I switch to a different camera, it goes right side up, But...  If I try to use the camera dolly, it switches back to the problem camera and goes upside down again.  But wait, theres more.  If I switch to another camera, and then move the dolly and see it go upside down, then if I try to do a spot render, it renders from the other camera...
