I have been using Thunderbird for years and love the program. I was surprised today when I was writing a long email and the cursor kept ending up in the Subject heading instead of the body of the email. My typing continued in the subject heading. I had to manually move the cursor back to the body of the text. I noticed this happened every time the email was automatically saved. It was very disconcerting to be looking at my keyboard then whenever I looked up, the text kept appearing in the subject heading. There is obviously a bug in the software and the only answer I can figure out to fix this until it is corrected is to disable the Auto Save function. How do I do this? I would report this to anyone interested in resolving bugs in Thunderbird, but I could not find who or how to contact the developers.
