Yes. That was a typo. I meant vtkRenderWindow::SetCurrentCursor( 
VTK_CURSOR_CROSSHAIR );

Yes. I did not implement it on the Carbon/Cocoa. Please go ahead and add 
the cocoa version if you have time.

At the time I guess I left that open since our software (VolView) did 
not have a Carbon /Cocoa interface on the mac and instead defaulted to 
an X11 application on mac. I think the crosshair defaults to some other 
cursor on carbon/cocoa.
