Hey everyone ~ and thanks in advance for your support I'm running Thunderbird on a 2021 MacBook Pro since a month or so ago. *I have trouble printing when I have "display message thread" turned on - the little staircase icon & the print icon is grayed out whether I try to print from an email directly or from the command sequence File, Print. I have restarted my laptop, turned my printer on and off ~ and have no problems printing from other applications - but this is a conundrum! I've thought of reinstalling but do not want to loose emails (( ! )) All suggestions greatly appreciated. Leslie
