Four Wall Cave using two client cluster

[JB_HP_Viz]

Jeff,

I think I have the correct settings now by defining four windows
#Define windows
leftWindow = viz.addWindow()
bottomWindow = viz.addWindow()
rightWindow = viz.addWindow()
frontWindow = viz.addWindow()

and then for each client in the cluster.MaskedContext I setup to split the display in two and then display in Fullscreen so each projector
will receive the correct output from the computer. On CLIENT2 I get a subwindow in the top right corner. Other than that problem everything
displays correctly. any idea why I would get the sub-window?

Here is the code I used:

import viz
import vizcave
import viztracker

# Declare constants defining the CAVE dimensions
W = 3.048       # 10 feet wide
H = 2.286       # 7.5 feet tall
D = 3.048       # 10 feet deep
W2 = W/2.0
C0 = -W2,H,0     # Front  Wall: C1,C2,C5,C6
C1 = -W2,H,D     # Left   Wall: C0,C1,C4,C5
C2 = W2,H,D      # Right  Wall: C2,C3,C6,C7
C3 = W2,H,0
C4 = -W2,0,0
C5 = -W2,0,D
C6 = W2,0,D
C7 = W2,0,0

#Create front wall
FrontWall = vizcave.Wall(   upperLeft=C1, 
                             upperRight=C2,
                             lowerLeft=C5,  
                             lowerRight=C6, 
                             name='Front Wall' )

#Create left wall
LeftWall  = vizcave.Wall(   upperLeft=C0,
                             upperRight=C1,
                             lowerLeft=C4, 
                             lowerRight=C5,
                             name='Left Wall' )

#Create right wall
RightWall = vizcave.Wall(   upperLeft=C2,
                             upperRight=C3,
                             lowerLeft=C6,
                             lowerRight=C7,
                             name='Right Wall' )

#Create bottom wall
BottomWall = vizcave.Wall(  upperLeft=C5,
                             upperRight=C6,
                             lowerLeft=C4,
                             lowerRight=C7,
                             name='Bottom Wall' )

#Initialize graphics window
viz.go()

#Create cave object
cave = vizcave.Cave()

#Define windows
leftWindow = viz.addWindow()
bottomWindow = viz.addWindow()
rightWindow = viz.addWindow()
frontWindow = viz.addWindow()
