#22030 — Remanents of Thunderbird

I recently discovered that when you close Thunderbird there are several 
parts are left in the device manager.  There are four which I suspect 
are internet accesses to the four accounts I have in Thunderbird.

Is this action new or is it the cause of the incomplete shutdowns I 
occasionally experience.  In complete = all active programs and desktop 
shut down but the power lights of the laptop stay one until you do a 
hard shutdown. ie hold the power key

Presumably you meant "Task Manager"?

When I close TB, all five of its processes close completely in a couple 
of seconds.

If you do file/work-offline before exiting do they close?

You possibly enabled "When Thunderbird is closed, move it to the tray".

No, did you tweak your Windows power configuration? Try resetting it.

I've had the same thing - well, external USB power remaining on - but
I've not connected it to Thunderbird; laptop appears fully shut down,
but external fan tray (and its blue light) remain on. But it _does_ shut
off eventually - but I think it can be a minute or two (possibly even
more) after the laptop appears to have shut off.

If you're on Windows...

Or check BIOS settings:

Thanks, but those appear to be about a BIOS setting which leaves the USB
ports powered when the machine is off (e. g. for charging things).

This might well sort knuttle's question.

Mine - which isn't a problem, really; I only mentioned it as a
_possible_ explanation for knuttle's observation - is that the port
_does_ go off on the rare occasions when I shut down - but, takes ages -
possibly a minute or two, possibly more - after the laptop has xeased
all signs of life.

Often at work I wish they'd pay me what I'm worth, but sometimes I'm
glad they don't. (BrritSki, in uk.media.radio.archers, on 2000-12-25.)

Here is a picture.

The multi-process configuration, has individual children with fixed purposes.
For example, two of the processes are "tab", which means they have something
to do with the support of "tabbed views". One of the processes is "GPU", meaning
something to do with the graphics used, OpenGL, or whatever the flavor of display
stack is this week.

These processes are NOT assigned one per account. If you went from four accounts
to one account, the shuffle does not change. The processes support "functions",
some of the child processes, if killed, they re-fork. It is when the parent dies,
it harvests all the children (or it is supposed to). The tasking model on
Windows is not perfect, so when I use terminology like this, it might not be
precise enough for the job. A good OS would have a PPID field (Parent Process ID),
making it easy for the user to spot the parent. I have to resort to using
Process Explorer, where the Parent is to the left, and the Children are indented.

As for what is happening, yes, Thunderbird is in the tray, but it is also at full
power. It's not a Metro.App in Suspend state. And I am not claiming it should be
that way either. The state diagram for Metro.Apps, is not drawn properly, as
when a Suspended app is headed for a doom situation, it is harvested. It should
be "easy to kill" if Suspended. Running at full power, does not block the OS from
doing things. It should be no different than if Thunderbird was on the screen.
While you can assert a multi-media bit to "hold the screen open when playing a movie",
the child processes in this case, may not even have the movie player. I'm not sure
what the movie player child would have for a label.

What I'm seeing is not entirely abnormal, and someone will have to judge whether
this Tray situation is correct or not. I can't really say, one way or another.
I presume there is a good reason for this Tray feature, drumming fingers
now, trying to think how no state change and move to Tray is "goodness".

That is exactly what I am seeing.  Why do they not close when 
Thunderbird is closed?

Because the tick box to do that has been selected ...

OP:
Thanks:  I suspected there was a simple toggle but could not find it.
