That is exactly what he was talking about, and I also agree with his prognosis. The screen is not sitting properly in its place, likely because its place is tweaked.

Indeed. However, the ones that were introduced after the EOS 3 (such as the type S) will cause the camera to meter improperly, so if you use your in-camera meter, take care to get one that works with the 3's meter.

Personally, I got the S screen anyhow, since I don't ever use my in-camera meter. Works like a charm.
