[vtkusers] Force a 2D actor to be on top?

I have two vtkActor2Ds that I want to display in the same
window. One is an image, the other is a contour (generated
by vtkMarchingSquares) from that image.
At home, when I just add each to the renderer (using Tcl) thusly:
ren1 AddActor2D vhdImageActor
ren1 AddActor2D vhdContourActor
all is well, and the contour appears "on top" of the image.
At work, only the image actor appears. When I comment out
the first line above, the contour appears, so it seems the
image actor is "on top" of the contour actor.
Other than the obvious conclusion that I should only work
from home, what is the best way to force the contour actor
to be "on top?"
