i have never in my life seen a print like that -- looks like a series of test strips. Did all the frames come out like this?
This has nothing to do with the red window. This is not fogging. This is -- cripes, I dunno what it is -- looks as if the shutter was a horizontal-running Focal plane shutter with a bad case of the stutters. And you say the problem is on the edges of the film too?
Tell you what -- try a second roll of film, use the red window with a bit of black electrical tape over it between exposures. Report back and tell us what sort of camera you are using as well, and use fresh film.
