I'm guessing it depends on the language. In spanish we have only one type of accent and only in vowels: áéíóú, and the ñ. The ñ is right next to the "L" key, and the tilde (accent) is either right next to the ñ or on top of it. This adds some sort of complexity, but in my experience, the average user simple expects the key to be "where it always was" and I've had to "fix the problem" (changing the input method) many many times. To answer your question I think that the amount of users that actually take note of what happened and understand it enough to fix it again is minimal, the rest just expect it to work and ask for help when it doesn't. There are also a lot of variations of spanish keyboards, so it just makes the matter more complicated... I use *unix, Windows and OSx almost interchangeably and know how to change the input language in most of them to ISO spanish spanish quite quickly, but I'm not representative in that regard. Slightly offtopic but the spanish spanish keyboard layout is extremely comfortable for programming...
