Yikes....myths are revived under our very eyes!....;-))
All my SLR's thusfar had film windows (and all had plastic backs, to 
kill another myth before it sticks out its ugly head....;-)).
Never had any problems with fogging.

Mmm....this 'IR fogs, the visible part does not' does not apply to 
HIE....EIR is therefore different in this respect?
I had fogged HIE when a shop stored exposed film (leader in) without 
cannister....but that involved visible as well....anyone ever stored 
exposed HIE (leader in) in a IR-leaking, yet visibly opaque 
cannister. 
(I believe I once fogged HIE in such a cannister, but that was a
piece of bare film, ripped off while trying to squeeze out another
frame in my Horizon 202; so the felt light trap was not involved in
this situation)

With HIE, it doesn't matter if film is in or out of the cartridge....is 
EIR different in this respect? Is it definately only the visible part 
of the spectrum that is related to this light piping effect?
I heard the argument of the IR-layer being covered by the visible 
layers, hence being protected....but if visible light is the fogging 
source, then this argument is not valid....mmm....
