David and John,

I saw that you werew changing the build process for vtk's python bindings on the pc, so I'll direct
my question towards you.

I am trying to build the python bindings for vtk on a pc with Windows2000 (shouldn't matter, but I
have hit upon some other Win2000 library problems).  The normal python bindings work fine, but when I
use TkRenderWidget my program crashes.  The build process seems to build the TkRenderWidget dll fine.

Since this is the TkRenderWidget, my first assumption is that vtk and python are building with
different versions of tcl/tk.  (Any time TkRenderWidget doesn't work in tcl the cause is usually that
vtk is built against one version and is executing against a different version.) By default, vtk is
building with tcl 8.2 and it looks like python 2.0 ships with tcl 8.3.

Are you building off the vtk repository with python 2.0? Do I need to go grab the source for tcl 8.3
so I can build vtk with the same version of tcl that python ships with?
