Same problem here on WinXP. I thought it had to do with
installing Office XP SP1, SP2, and Word update but not
sure now. All was ok until I installed them. I have not
been able to fix it by a system restore, reinstalling IE
6, or uninstalling Office. You can reinstall or repair IE
6, see http://support.microsoft.com/default.aspx?
