The crosshair is rendered in last used color or is even not visible if an image with binary outline is in a lower layer.
It only appears in the renderwindow where the image is visible.
Step to reproduce this bug:
- load no_name.nrrd
- load pointset.mps (* change opacity to 1.0)
->crosshair should now be red
- set outline binary to true
->crosshair disappears (or is black)
There is also a strange behavior if you load no_name.nrrd twice (without poinset) and change to outline binary true and use another for one the images.
