Alt-Tab fixes the problem, however it happens often and randomly. Reproducible: Didn't try
Happens for me as well [On trunk], a bit less often, though I believe there is another bug somewhere with this issue (QA-Person, please Search for a dupe somewhere before confirming this bug).

this happens to other apps besides thunderbird and I've heard it's a windows bug, basically.

I still have this problem with the latest (1.5) version of Thunderbird, however, for Firefox, sometimes it will disappear completly from the taskbar, only to reappear again after and Alt+Task.
I see this behavior also, both with 1.0.7 and 1.5b1. Thunderbird is still running but disappears from the Windows taskbar. I can still get to it with alt-tab. I haven't noticed any pattern about when it does and doesn't happen. FYI, I keep my taskbar vertical along the right side of the screen.
Confirming this bug on TB 1.5 (final build, non-updated RC2) German unter Win XP Pro SP2 German, classic theme, desktop and start menu. Task bar is unlocked and set to default behaviour (screen bottom, keep visible, keep in forground). TB main window icon disappears at times when * an external link (i.e. http:// address) in the mail preview pane is clicked and the launched app window comes into the foreground; * a compose new mail window is firts launched and comes into the foreground. Steps to reproduce: none, behaviour is random. The pattern indicated above seems to link the problem to the main window losing focus (which explains why it reappears when it gets focus back through task switching). As to this being a Windows bug: I've been running nearly every task bar enabled Windows flavour since 1996 (at home and at work, as an admin and as a user) and have never noticed this behaviour in an application window before.
The last days I have seen this bug multiple times on different computers where WinXP is installed. David, it only happens for Firefox and Thunderbird. Both are the latest builds from the 1.8 branch. No other applications are affected. So I don't believe that it is a bug in Windows. Does anyone use the classic style instead of Luna? Should bug 345856 (Firefox) be duped to this one? Which component we have to use than?

Ever confirmed: true
Randomly AND frequently!! Disappears behind other applications, gone from taskbar, so to use it must minimize everything else, one at a time, to get to it. THEN the icon reappears on the taskbar but at the end, as if it were opened just now. Cannot use "show desktop" to find it, must minimize others one by one.
(In reply to comment #8) > Randomly AND frequently!! Disappears behind other applications, gone from If this really happens frequently to you please have a closer look what you are doing. Clicking an external link, opening a helper application or something else. I believe some user action or software combination could be the cause.
Summary: Changes places on taskbar or non visable on taskbar-randomly → Thunderbird sometimes not visible on taskbar
NOT Thunderbird!! I was the one who made the complaint re FIREFOX!!!! As to what I am doing at the time when it disappears, NOTHING!! Use FF for a while, then go to calendar app, or email, then look for FF to go back to, and it's GONE!!!! Have to then minimize all other apps to find it!!! And why is it so damn SLOW??? When I do find it, can do a few clicks, then it STOPS and sits there for about 2 or 3 MINUTES!! I get tired of staring at nothing, so go do something else, then have to go through all that AGAIN!!! The "finding" of it and the WAITING for it to wake up!!! I read on a blog somewhere that Windows steals memory from FF and that FF has to get it back, thus the wait. BUT the "fixes" given there were totally incomprehensible and I could not even find WHERE to do the fixes. What settings can be changed? (1) To stop it from disappearing, and (2) To stop it from sleeping on the job?
As to this comment: "...please have a closer look what you are doing. Clicking an external link, opening a helper application or something else. I believe some user action or software combination could be the cause." Am I then not supposed to DO anything? Actually, it happens when I am NOT doing anything with FF.
> NOT Thunderbird!! I was the one who made the complaint re FIREFOX!!!! So product of this bug was initially set as Thunderbird. And there was nothing mentioned about Firefox. So please be objectiv! I will change it to Firefox and OS integration because it will be better suited and enhance the summary.(In reply to comment #10) > Use FF for a while, then go to calendar app, or email, then look for FF to go > back to, and it's GONE!!!! > Have to then minimize all other apps to find it!!! Why you have to minimize all other applications when Alt+Tab fixes it for you? What happens in such a state if you close another application and new space gets free on the taskbar? Does the Firefox button comes back? Please tell us something about your hardware configuration.

Some minutes ago I had the behavior again. The Firefox taskbar button was hidden while Firefox is running and listed within the task manager. It happend with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:188.8.131.52pre) Gecko/20071030 BonEcho/184.108.40.206pre Is there any change or better which way I have to use to track this problem?
