The edge of the window in the Star Wars frame is in shadow so it is not noticable and is therefore not an issue. The edge of the window in ESB is very much lit up, very noticable and therefore an issue.

So, most of the other cropped shots should not have been an issue when, in many, the frame is either lit as darkly as it was in ANH or is completely unseen? I probably should have explained that i was talking about ALL the cropped shots and not just the one image i posted when i said about the fourth wall argument and it being invalid. I wasn't actually trying to be an ass or anything like that. (click on the images to view them larger)
