92670 - Intermittently, mail composer in plain text stops performing line wrap

Status: VERIFIED DUPLICATE of bug 83378

(MailNews Core :: Composition, defect)

Description

[Peter B. West]

From Bugzilla Helper:

BuildID:    2001072623

Sometimes in recent (approx 3 weeks) builds, the plain text mail composer ceases
to perform line wrap.  This is usually preceded by a quirk in the newline
behaviour on empty lines, typically when inserting empty lines beneath quoted
text when replying.  I can't describe this exactly, but I think that the cursor
is displaced to an unexpected line following the entry of a newline.

After noticing this quirk, I find that line wrapping has ceased.  Closing the
mail composer and the mail window, and re-opening does not restore the line
wrapping.  Closing and re-starting mozilla does restore it.

Reproducible: Sometimes
Steps to Reproduce:
1.Reply to a message
2.Introduce a few empty lines after the quoted text, but before the signature
3.Type or paste long lines of text

Actual Results:  Cursor behaves strangely on typing of newlines for empty lines.
 I can't be sure whether the newline is inserted, but the cursor appears on the
wrong line, usually below the expected position.

long lines do not wrap at all.

Expected Results:  Newline entry inserts newline and places cursor at the
beginning of the line following the insertion.
Line wrapping is honoured.
