As far as I can tell, Mail Merge (as well as data sources) is broken in OpenOffice on 10.04. There is no
View | Data Sources menu option, and the shortcut for
Data Sources F4 does nothing.
In addition the Mail Merge Wizard doesn't allow any 'Address Book' to actually be added (the
OK button is never enabled).
Add Database File... on the
Database tab of
Insert | Fields | Other (Ctrl+F2) is not working.
