Hi, RogerM. I can;t remember how it works in XP, but I remember having the problem. Check in the Tools/Templates and Add-ins to see if the template has Automatically update styles checked. Also, check Tols/Options for Keep track of Formatting, and the Autoformat and "Autoformat as you type" for any check boxes having to do with formatting or styles. Uncheck one at a time and see if that solves the problem. And, let me know if something works!

Best,
