Comment 6 for bug 810769

I'm running Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.8) Gecko/20100227 Thunderbird/3.0.3 and seeing the same phenomenon as Joe Sabash in comment 1. In my case it's emails; I cannot swear they would never get sent, since when I have found some I have always sent them - which works every time.

I don't see a setting "Send in Background, preference mailnews.sendInBackground"
