Instead, it opens on display 1. Reproducible: Always Steps to Reproduce: 1. Two displays. 2. Mailbox window on display 1 3. Compose message window on display 2 4. Try to change the To: to something else by clicking on it. Actual Results: To: CC: BCC: dropdown menu appears NOT at the point I click, but instead appears on the other display. Expected Results: To: CC: BCC: dropdown should appear at the point of clicking, within the message Compose window.

Probably fixed by bug 314279, which will be in Thunderbird 3.0

Indeed.
