I am trying to make use of this widget. I have no problems with it
under Windows, but when I try to work under Linux (Xorg-6.8.2) the
widget doesn't work (even the sample code GUI/*/ImagePlaneWidget.*). I
tried using VTK-4.2 and 4.4, Python and Tcl, x86 and x86_64. Any ideas
what is wrong? Is it a bug?
