From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9.5+) Gecko/20011101 BuildID: 2001110103 I have minimized the new big mail-header. But since them my headers have gone. (I mean that I've dont see anymore the sender, the newsgroups, the user-agent-string and so on.) I have tried to change view\headers\all - normal but nothing is happend. Reproducible: Always Steps to Reproduce: Minimize the Header (the part of the mailer who shows the user-agent-string)

I'm seeing this too on Linux rpm build 2001110100, changing the View->Headers from All to Normal does not fix it. There is a black line that appears only a couple pixels deep (if that) when clicking from the welcome screen to a message that should display header info. Screenshot appended.
