I'm thinking nobody has any specific answers to this, so here's some general
troubleshooting info.
Are you using Office 2001 or 98? What updates have you applied?
Have you tried renaming the Normal template (in Apps: Office: Templates) and
the Word Settings file (in System Folder: Preferences: (maybe in Microsoft
folder)? Close Word, rename them both, then reopen. Word will have created
new ones. These two files hold a lot of settings and can become corrupted.
This link is about missing menus (not your problem) but has specific
directions for testing the Normal template and the Settings file, and for
restoring your customizations if it turns out one of those is corrupt.
