Anyone know how to make the sheet tabs and horizontal scroll bar show up at the bottom?

I created a workbook for my mom's work on Excel 2000 containing 5 different sheets, which I can navigate to by clicking the tabs at the bottom. However, my mom can't see the tabs (or the horizontal scroll bar) using Excel 2003. There's nothing else at the bottom except the status bar. I got her to check Tools>Options>"View", but both the sheet tabs and horizontal scroll bar options are checked to be shown. Is there something else I can tell her to do?
