How to reproduce:
- Load an image
- Open Measurement View and select one figure ( DO NOT DRAW IT )
- the data node with the figure appears as child of the image node
- delete the image node
- the figure will be also deleted, but the 2D Renderwindow interaction is lost completely
--> Load an image again : the crosshair cannot be moved by mouse click (even after global reinit )
- the figure will be also deleted, but the 2D Renderwindow interaction is lost completely
How to recover:
- open Measurement View, select some figure and draw it. Then the interaction is active again
