Office XP and forms

[cking]

we have a review form with text areas written in word, we have a user that opens it useing office xp and can modify the file and save it just fine but if they go to spell check the option is greyed out and they can't use the F7 key, it spell checks normal documents just fine I have reinstalled office and that did not correct the problem is this just an issue with xp of is it correctable?
