Vincent Nicolas,

You can use "pack forget" in place of "wm withdraw" and pack again 
on demand. Without destroying, the error would not be produced until 
the program termination.

I found a misleading behavior of configure of vtk***TkWidgets that 
seems to be related to the problem you described. I reported it on 
the vtkusers list and have got no response for more than a year. 
I was afraid that some tricks in freeing the widgets' resources 
might make them too hard to be fixed.

Regards
