When sending email to a number of addresses I want to be able to highlite all addresses in an address book and drop it in one address line using BCC. I used to be able to do this with older version but not with new auto update of version 45. Now when I drag and drop a number of addresses into address line it pastes incorrectly and also puts each address on a separate address line. This does not happen with a copy of Thunderbird I use on my home computer. This is a recent problem. Need help!
