Im running AutoCAD 2005, while copying an item, as I drag past other items with object snaps on, as it is selecting snap points AutoCAD will crash. With previous versions of AutoCAD I have had this problem while Apparent Intersection or Insertion are selected in the settings. These options are not selected and the problem seems more random, even while snapping to a mid point. I've only noticed the problem while copying. Also it is only a 2D drawing.
