For reasons I don't understand, TBird has suddenly changed its behavior in displaying plain-text messages as they are being composed. It used to be that TBird would wrap long lines to the window width, whatever that happened to be. If for example, I reduced the width of the window, TBird would automatically rewrap the lines to fit.
Now, however, TBird uses a specific width (NOT character count) and wraps all lines to that width. If I reduce the window width, a horizontal scroll bar appears and the lines do not rewrap. If I increase the window width, TBird continues to wrap the lines at its chosen width, leaving blank space to the right of the lines. I've made no changes to about:config.
Why is it doing this, and how can I stop it?
Settings from about:config are:
mail.compose.wrap_to_window_width; true
mail.wrap_long_lines; true
mailnews.display.disable_format_flowed_support; false
mailnews.send_plaintext_flowed; true
plain_text.wrap_long_lines; false
I've tried TBird with the last setting = true, but this didn't help. I've also tried TBird with addons disabled; again, no better.
