Hey, one at a time!!!  Greg, Larry, etc. take a number.  Now I
am answering to Paul:

Does that mean that it is located 44 mm from the eye in a RB viewer?
What's that talk about the window being at 7 feet?

The "stereo window" is not the same as the slide mask.  The slide
mask is a real object located at a specific distance from the
eyes (in the viewer)  This mask creates a frame of reference that
resembles a real window (hence the name) of a certain size and
location from the observer when the image is viewed stereoscopically.  
The window is just a frame of reference.  It is not a real object.
