What is this icon on the task bar?

1

I'm talking about the 3rd icon from the left, that looks sort of like an envelope. It's curious, because I often get several of these, but they mysteriously "evaporate" when you mouse over them, so it's impossible to "ask" them what they are.

Looks like a "New mail" icon shown by Thunderbird that crashed.

(If a program crashes, Explorer's notification area doesn't notice that until it needs to send an event like mouse move to the program, at which point it removes the dead icon.)

Except that Thunderbird has not crashed (that I know of). It's generally not (visibly) running when these appear, nor had I left it running. (When I check just now with Process Explorer I see that Thunderbird is running in background, though. I guess it must start on a timer and then later kill itself or some such.) – Daniel R Hicks – 2013-08-24T13:09:04.120
