[vtkusers] Destroying TK Widget ...

[Vincent Nicolas]

Hi all,

When I'm destroying a tkwidget (vtkTkImageViewerWidget, vtkTkImageWindowWidget or vtkTkRenderWidget) a got XWindow error and the program exit. 
I don't see where is the problem as I delete all the VTK objects before destroying these tkwidgets.
I've tried many different manners and this error only appears if I create more than one tkwidget (of any type).

I need to destroy these tkwidget on runtime to be able to change the interface of the program on runtime.

I'm using VTK 4.0 with a GForce 3 graphic card (with NVidia's drivers)

Here is the error :
X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 142 (GLX)
  Minor opcode of failed request: 5 (X_GLXMakeCurrent)
  Serial number of failed request: 1874
  Current serial number in output stream: 1874

Thanks for your help.

Vincent Nicolas.
