[vtkusers] Problem in using vtkOrientationMarkerWidget

[Dean Inglis]

Hi Jean-Do,

I dont get any strange behavior when I compile
and run your code when using Borland Dveloper Studio 2006,
latest VTK cvs, Release build on WinXP.  See attached
jpg.

Hi Dean,

thank for your help.
But a strange thing is that even when I apply your correction, I still get
the
same result. There must be another error I guess.
Any other idea?

A question : do you obtain the same result as me if you try the test I
joined at
the end of the first mail?
Forgot to mention, but I'm using vtk5.0.3 on WinXP compiled with VC7.1
