I just updated to DraftSight 2018 today. Previously, when I would draw a square/rectangle and select it, blue squares would appear in each of the corners and blue circles would appear at the center of each edge. If I would click the corners then the two line segments that make the corner would move, whereas if I selected the blue circles in the middle of an edge, then the entire rectangle would stretch. Unfortunately, now the blue circles do not appear and I can't seem to figure out why.
