You list the extensions "indicated", what option has these extensions specified? Are you editing with Word 2003 within Ultra Recall, or externally? From the list you provided, I would guess you are listing extensions for the Browser <tab> "File extensions to display in internal browser view" option...
If you Repair the database, is the problem resolved? Repair is accessed at
Tools | Compact and Repair... (just check the Repair database checkbox).
If the .urd file you have created is small and doesn't contain any sensitive information, please send it (before repairing) to
support@kinook.com in its present state, we would like to take a look at it (this isn't a known issue).
