My program is putting markers on all points of the polylines.I'm using the insert_at & set_at listeners to update my markers when the user is moving these points to a new location.Google maps API v3 provides an undo button when drawing a polyline.It works fine with set_at (repositioning my marker to it's original position); it does however not work with insert_at.
Is there a way to program behaviour of the undo button so I can remove the marker when using the undo button?
