I finally got the update to install, unfortunately. I tried installing
KB934180 manually, rather than automatically, and found it was hanging up on
FrontPage 2003. So, I uninstalled FrontPage, let the update run on the
remainder of Office 2003, and then reinstalled FrontPage. It worked.
However, now Outlook is a mess. Some of my email accounts no longer work
properly, and my Palm PDA won't sychronize with Outlook any more.
