[vtkusers] vtk and Java : problem when remove a vtkactor to a vtkrenderer or add avtkrenderer to a vtkrenderwindow

[Romain Ollivier]

  Thank you for your reply.
  I've tried to replace my code with your's but I still get :
  Xlib: unexpected async reply (sequence 0x5a1)!
Has anyone any idea about the way to solve this problem ? I think this is a
graphic card problem, but I'm not sure... I work with a VGA compatible
controler : nVidia Corporation NV25 [GeForce4 Ti4600]...

  Thanks for any help,

        Romain
