Sometime ago, not sure if it was in the 3.5 or 4.0 beta I was able to use the Thunderbird address book as a database table for mail merge etc. Since I have downloaded the 4.0 final I have not been able to get this functionality to work.
Was it killed somehow inadvertently or deliberately when the Linux enhancements to use Thunderbird address book were put in place, or am I just not getting it right?
Windows version of LibreOffice although the vewrsion may have been XP for the early success and 7 for the failures.
