What to do when Berkeley Mail "locks up"?

You might notice when you're typing text while in the mail program, the keyboard locks up a few characters into the fourth line. Why?

The problem is probably that you're not pressing the Enter key near the end of each line. The mail program does not give you a word processor which does automatic justification for you, it gives you a basic text entry device. The input buffer is only 256 characters long, so after three 80-column lines and 16 additional characters in the fourth line, you've filled up the keyboard buffer and cannot type any more characters. The lines may appear to wrap on the screen, but it's happening *only* on the screen. The input line is perceived by the computer as one long line. If you do send mail like this, it will appear as badly formatted very long lines to the recipient, and may confuse other mailers.

If you press the Enter (or Return) key when the cursor gets around an inch or so from the right margin, you'll prevent this from happening, and your letter will look much better when the recipient reads it.
