Mail Preferences Pane Not Displaying
Hello everyone! I have a question regarding Mail Preferences on my MacBook Pro (Late 2016 - 15"). When I open the Mail Preferences pane (or any of its sub-menus) from the Mail application, the following type of window is shown (here is the 'signatures' pane):
Has anyone else experienced this type of issue? What ideas do you all have to resolve the situation? I did update my Mac to the latest OS (10.14.1) after I first noted the issue, and I have restarted Mail several times.
With thanks,
