[vtkusers] linux + wxpython : Multiple wxVTKrenderWindows problem

[Fabrice Vincent]

Hello,

I am trying to use 2 wxVTKRenderWindow on a linux system

Whenever I try to interact with the second renderwindow the X server

crashes. The same problem occurs on two computers with more or less the

same configuration.

Here is one of the configuration :

VTK 3.2
WXPython 2.3.1
Python 2.1.1
Redhat 7.2
NVidia Quadro 2

Any suggestion ?

Thanks

Fabrice
