This happens to me when I use IMAP to access a Microsoft Exchange server, and I see Exchange's very long proprietary addresses, but you can reproduce it by making the width of your window narrower than a normal email address. Reproducible: Always Steps to Reproduce: 1. Send yourself an email with a very long address 2. Open the message in a message window 3. Set the window's width narrower than the address Actual Results: The right scrollbar and the throbber disappear. You can't scroll the message using the mouse. Expected Results: The scrollbar should always be visible (if the message is long enough to need one). The throbber shouldn't be pushed off by a long address, either, but might be pushed off by the other toolbar items. I'll attach a screenshot.
The bug to which this is duped is primarily about the 3-pane window, but there are screen-captures there for the standalone window as well. This is a long-known problem (and used to be worse, since it happened for long Subject: headers as well). *** This bug has been marked as a duplicate of 91662 ***
