Civil Handles Disappear with Zoom Change

My civil handles are not always visible.  They seem to be visible at only certain zoom ratios.  I don’t understand this relationship and think this is a bug.  I am working with an open roads SS3 horizontal alignment.  “Handles” are enabled and the alignment is selected.  The civil handles appear and disappear as I change zoom ratios (see video, and dgn).  I have tried two different computers so I don’t think it is a video card issues.  How do I correct this problem?
