I just installed Thunderbird version 115, and it's a mess. When I attempt to write a message, the background color is black, making it almost impossible for me to read what I am typing. I've tried changing it through Settings/Composition/HTML Style, but that didn't work. I selected text color Black and background color white, but if I left the Sending Format as automatic, my new written messages still have black text on a black background. If I also change the Sending Format to Only HTML, then my new written messages have white text on a black background -- the exact OPPOSITE of what I have selected. (And yes, I have checked repeatedly. I have selected black text on a white background.) I'm running Windows 11 Home. I'd greatly appreciate any ideas on how to fix the colors of my messages. Thanks!
