I don't believe that this is correct.  I've never covered the window on any
of the past 100+ rolls of HIE I've shot and never seen a fogging problem.
If the window on the back of your camera is a problem, then that indicates
that there is a problem with your camera.

As far as the fogging is concerned, I don't believe that there is any way to
tell if you or the lab fogged the film.  Changing bags, for the most part,
are not IR opaque, so that may be your problem.

Complicating the situation is the fact that many places that develop film
haven't a clue as to how to handle IR film (I will assume that you gave the
film to them in the original cannister, with the warning on the lid).  If
you gave it to a custom lab, however, I would have to assume that they might
be more knowledgeable.

Best is to do it yourself.  Long before I had an enlarger (about 150 years
ago <g>), I developed my own film, then made contact sheets with a 40 watt
lightbulb in my bathroom.  I can't imagine giving anyone a chance to screw
up my negatives.
