P3D stereo shows

["Farfl's house" <lederman@xxxxxxxxxxxx>]

Poor Keith Wilson!
Those bleedin' unbelievers!!!
I have quite a different problem with stereo shows, and perhaps someone
can help me while helping Keith, or maybe after helping Keith, or.....
anyways, when I give a stereo slide show, often I find there is blue
edging around some of the images. Is this due to the fact that the
projecter isn't entirely flush with the screen, or does it have to do
with the polarizing, or is something out of adjustment, or has someone
slipped LSD into my coffee?
I'm using a stereo FED projector with the supplied glasses.
Another question, totally related; 
these slide presentations are for select gatherings only, as I only have
about four or five pairs of glasses. Where can I purchase more glasses
for the FED setup?
Anxiously,
Steven
