Mispronunciation

Shouldn't someone tell Marcie Latimer that the word "entrepreneurial" has an I in it? She seems to think that it's pronounced "entreprenural", rather than "entreprenur-ee-al". She has seemed convinced of this mispronunciation for so long, but the funny thing is that even so, she still stumbles over it whenever she has to say it.
Or am I expecting too much?
