and click on International, select the Language tab, is English at the top of the list?
Then, at the Input Menu tab, scroll down to U.S.. Is U.S. or U.S. Extended selected - and all others not selected?
While you are here, put a check in the "Show Input Menu in Menu Bar" and that way you will have easy access to the character map.
