Upon returning to Thunderbird, both objects are displayed, albeit with no internal content. Reproducible: Always Steps to Reproduce: 1. From the 'Mail & Newsgroups' window, compose a new message. (this opens a new 'Write' window) 2. Send a test message. Click SEND (or Command+Return)... 3. Before the "Sending" dialog and the "Write" window are dismissed, press Command+h to hide the Thunderbird application. 4. Wait a few seconds until the message has been sent. 5. Navigate back to the Thunderbird application. Actual Results: You'll find that the "Sending" dialog and the "Write" window are still "open". Expected Results: Both the "Sending" dialog and the "Write" window should be properly dismissed, even if the Thunderbird application is "hidden" It takes up to 5 seconds for the remote mail server to process messages being sent. Consequently, it is useful to be able to hide Thunderbird in order to resume work in other applications, even while the message is being sent. The affected system has no Thunderbird extensions, themes (beyond the default one), or plugins.
Reproductible with Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b13pre) Gecko/20110227 Thunderbird/3.3a3pre
Sounds same problem as bug 525335.
soooo, any movement on actually fixing this bug? I reported it in October 2009, and the PR was completely ignored for 1.5 years.
Just for the record, this bug is still present in TB 5.0b1.
Confirmed Reproducible: Always with Thunderbird nightly 2012-03-17-03-00-22-comm-central on Mac OS 10.6.8 using the steps in comment 0.
