Been using Thunderbird for years but since this latest update, when I create a new email, it can not find any of my contacts in the address books however, if I use the F9 key, I get a list of the contacts on the left hand side. You can search the contacts and double click a contact and an address will be added. However, if the contact ask two or more addresses, only the first one is added. This seems a massive step backwards if this is a design feature. I have 3 machines all doing the same thing. Any pointers would be appreciated.
