In the Shinra Building on the 62nd floor where you have to guess the password. I wanted the materia prize so went to make sure I had the first guess right.
Anyway, checking the books in the rooms, I came up with a combination. Went to the mayor, but none of the words matched what I'd written down, so went back and checked twice again.
Then it clicked, there's TWO books on every shelf. I for some reason assumed there was only one per shelf.
Got the Elemental Materia now, but that really was driving me nuts, how could I be so dumb?! 
Any of you done stupid things like that while trying to solve puzzles or whatever in the game?
