Word and Excel Cut Off Letters

I have a user that has the ends of words cutoff inside Excel cells or Word table cells. This computer is setup identically to the rest of the office and is the only computer that has the problem. The problem occurs regardless of who is logged in.All of the fonts have been replaced with the original fonts from the Windows XP disk. I’ve looked in the Usenet groups and in MS Technet and KB with no luck finding a problem like this. Any suggestions that anyone has would be greatly appreciated.
