[vtkusers] error in startup script

[qxue at jouy.inra.fr]

Hello, all:
    When I use the TCL examples by vtk.exe (VTK4.4+XP), there is always an error
in startup script:
"object named:imageGrid, could not find requested method:GetOutputPort or the
method was called with incorrect arguments"
    What is wrong?
