There's been this mildly annoying light leak, top right, in my Rift since day 1. I though it was because it didn't fit my facial contours... Just now when I was cleaning the lenses I noticed an ever so thin, yet long gap on the outside where the interface meets the HMD. I pushed lightly on it and it went *click* ... the gap disappeared and now the irritating effect of the light catching some of the fresnal ridges on the opposite corner, has vanished. And its darker in general inside when I'm wearing it. Yay! Just thought I'd share.
