Assuming you have ScreenTips checked on the View tab of Tools | Options, try
turning the Document Map on and then off again. This must be done once per
document per Word session. See "WD2002: Footnote ScreenTip May Not Be
Displayed" at http://support.microsoft.com/?kbid=318865

All of a sudden, when I put the mouse pointer on the footnote reference
number, I cannot see the footnote text in the screen tip. Any idea?!
