Description

[Hyman Rosen]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.0rc1) Gecko/20020417
BuildID:    2002041711

When I reply to a newsgroup message and send my reply,
the composer window goes away, but a button for it is
still in the Windows taskbar. Pressing it has no effect.
If I open a new composer window and then close it
without sending the message, the taskbar button goes
away.

Reproducible: Always
Steps to Reproduce:
1. Reply to a newsgroup message. Send message.
2. Reply to a newsgroup message. Close window.

Actual Results:  After 1, a do-nothing composer button stays in the taskbar.
After 2, it goes away.

Expected Results:  The composer button should disappear from the taskbar
after the message is sent.

I have the same problem. Also using NT 4.0 (SP6), with Build 2002051006.
I get the problem with an ordinary Compose message, not only replies.

Attachment: Excerpt of a screenshot with the taskbar

This happens in the recent build 20020826, Moz. 1.1. After the email is sent,
"Compose (..." button stays in the taskbar. Right-click or left-click do
nothing, no window is hidden in the background.

To close this phantom you should can select "compose" from the main mail menu -
and then clese the new mail compose window - this will kill the button. 
Unfortunately, until now I found no way how to reproduce the problem.
