[Vincent Nicolas]

Thanks for your replies,

The problem with "forget" is the same than with "withdraw", the objects 
will always remain in memory.... And I cannot use them again to create a 
new vtkTkImageViewerWidget ...

I think I'll keep a list of all the viewers I've created and use them later 
if needed in place of destroying an creating new one.... It's not a good 
way of programming, but I don't have the time to start debuging the Tk classes.
