Comment 6 for bug 363983

I found out one thing that might be of interest but I don't really think so.

Today (at work where thunderbird starts) when posting to a newsgroup in thunderbird I saw, that for a very short time (because I am on a fast line) the progress bar for sending the post came up and it came up on the secondary display.
I am sure, I never moved it there. Maybe at startup thunderbird verifies somehow if the last seen desktop geometry is
available?

Anyhow, some applications seem to think they have to popout their messages some pixels left or right from the virtual
center of my monitors and not the center of my main screen.
