Maybe this option shouldn't be there. Why would you want to quit Thunderbird while writing a message. It's a usability issue, since every time I want to discard a message I go for the last option under that menu. Maybe exchanging the "Close" option for the "Quit" option as the last one on that menu should help. Thanks. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Thank you for the suggestion. This is resolved in current thunderbird trunk and currently available 3.0b1. And eventually in the released Thunderbird 3.  http://www.mozillamessaging.com/en-US/thunderbird/early_releases/
