Suddenly I can't select addresses from the addr book directly?
Cannot use the method of highlighting a name in the address book pane and clicking "add to" or any other action at the bottom of the list. I can use the "to" field and enter a partial name but this only works for 3 addressees.

I'm guessing from your description that you're talking about the Contacts Sidebar that appears in the Write window, and not the full Address Book?
Try Thunderbird in Safe Mode.

Does this change the behaviour you see with the adding of Contacts?
Also did a clean re-install of Tbird. Same behavior. Safe mode does not make it work.
