Bug: DragMode set to Control Polygon causes SubD surfaces to disappear

Dragging control points of a SubD surface with DragMode set to ControlPolygon causes the SubD surface to disappear. The control point that was dragged also disappears, but the rest of the control polygon remains visible.

I am using Version 7 (7.0.20314.3001, 11/9/2020)

Hi John - that has been fixed - to get out of this, for now, drag a very short distance then use the tab direction lock - that should free up the thing to work as expected.
