Sure! I should have done that in the first place. My problem is not covering the whole screen - that still works. It is when I try to cover a sub-window I have a problem, as shown in the following code:

import viz
viz.go()
env = viz.add('tankmaze.wrl')

UpperRightWindow = viz.add(viz.WINDOW)
# NEED TO TEST REPLACING THESE COMMANDS FOR VIZARD 4
UpperRightWindow.setPosition(0.5, 1.0)
UpperRightWindow.setSize(0.5, 0.5)
UpperRightWindow.visible(0,viz.SCREEN)
'''
quad = viz.addTexQuad(parent=viz.ORTHO, scale=[12.0, 10.0, 10.0],color=viz.BLACK)
quad.alpha(.5)
'''
vq = ViewQuad()    
#quad = viz.add(viz.TEXQUAD)
lake = viz.add('lake3.jpg')
#quad.billboard(viz.BILLBOARD_YAXIS)
#blackScreen = viz.addTexQuad(parent=viz.SCREEN,scale=[100.0]*3,color=viz.BLACK)
blackScreen = viz.addTexQuad(parent=viz.SCREEN,scale=[12.0, 10.0, 10.0],color=viz.BLACK)
blackScreen.setPosition([.5, .5, 0])
blackScreen.texture(lake)
blackScreen.alpha(0.0)

vizact.onkeydown(' ',blackScreen.runAction,vizact.fadeTo(1.0,time=2.0))

The quad covers the screen, but not the window. Normally I am only trying to cover the subwindow, but this shows the difference better.

Thanks,
