Windows 10. Thunderbird 102 Mail Merge add-on 9.2.0 I installed Mail merge add-on, enabled it. Before, one pressed File..Mail Merge and a dialog box appeared. (See attached image.) Now, it's Tools...Mail Merge, or Toolbar button, but instead of Mail Merge dialogue box, despite filling in the relevant fields, I get an error box stating "No recipients were specified. Please enter a recipient or newsgroup in the message area." (See attached image.) Have tried restarting Thunderbird, uninstalling add-on and reinstalling. no change. I used the old version successfully many times before. Has anyone any idea what is wrong here? Many thanks Dave Tennant
