Draft edit is invisible
TenFourBird seems to have gone off the rails somewhere. I was using 17.0.11, and kept having trouble with writing a long e-mail. TenFourBird kept trying to attach something where I had no attachments. In the process of that, it declined to update or save a draft. It lost my work. I downloaded 24.3.0 and installed it. Now I can't even see my saved draft to edit it. All I get when I click on the "Edit" button is the header bar with the red-orange-green balls on the left. The rest is invisible.
I'm going to move my e-mail files to another computer with Win 7 & 8 so I can get my work done and stay in touch with people. I'll give up on TenFourBird if this isn't fixed.
