51837 - Text cursor vanishes when composing message

Status: VERIFIED DUPLICATE of bug 52150

(MailNews Core :: Composition, defect, P2)

Description

[Michael Collette]

This one JUST showed up in build 2000090704, as I just got through composing
messages in the previous day's build without this problem.  It has a problem in
both HTML and plain text editing.

To replicate: Open a new message composition window.  Type a few lines, then
press enter to get yourself down about 15-20 lines.  Continue typing, and you'll
notice that the cursor is no longer visible.

A fix was checked in some hours later.
Dup of 51747 "Caret doesn't render at the end of line."

Although the cursor problem reported in Bug 51747 appears to have been fixed,
the problem got a whole lot worse for Composer.  I'm no longer getting any
cursor at all in there.  Mail composition now appears to be working correctly.
These look related, and the symptoms spelled out in this bug have a closer
resemblance to what I'm seeing with Composer than 51747.

BTW, shouldn't I be able to change the component this bug effects?  When trying
to change the Product to Browser the Components listing doesn't update.  Is this
a Bugzilla bug that needs reported, or am I missing something?

Reopening bug, and adding myself to the cc.

This is a dup of the focus bug relating to new composer/message windows. Can't
find the bug right now.

New twist to this bug as of build 2000091108.  When opening up a new composition
window the cursor is with the ya the whole time, and everything looks to be
working as it should.  Replying to a Usenet post though brings up a composition
window without any cursor at all.  Composer itself still have no cursor at any
point.

trudelle. saari sfraser can help explain the underlying issue

To see what's happening, here, add this CSS to your global.css file in the skin 
you are using:

:focus {
    -moz-outline: thin dotted red !important;
}

Now, in a mail compose window, do the following:

1. click in subject line to focus it. Note the red border.
2. hit tab to focus the content. Note that the content is momentarily focussed
   (the caret appears briefly, menus briefly enable on Mac), then focus bounces
   back to the container for the subject line (the red outline goes back to
   the subject, but is slightly bigger than before).

So, focus is royally hosed in this window.

Fixed the problem in mail compose, a JS typo. Composer looks like a different 
issue.
