I'm not sure how or why, but I have many image pairs shot with a twin Ricoh 
Shotmaster II rig.  I use an Ekeren 5X (not a 5XR) viewer, and I just drop 
in the commercially mounted slides.  They look great, and the image does 
*not* appear in front of the window.  Possibly I've had the cameras toed in 
slightly all the time, but considering I've changed brackets several times, 
this seems unlikely.

Also, I keep the left and right slides in adjacent stacks in a regular 35mm 
slide storage box.  It's very quick and easy to drop in the left and right 
slides, and to remove them and re-stack them.
