I hate this bug. It has to be the only thing that makes using Mozilla Thunderbird such a pain in the ass. It’s disapointing that it has been open for ~3 years now and still not fixed, or apparently understood by the developers.
When sending an email, after the mail is sent via SMTP, it gets copied to the designated IMAP Sent Items folder. The email generally gets copied OK to the folder, but hangs the sending window until you cancel the email, and tell it to close and cancel about 3 times. It should only be 1 click to send, and forget about the client doing it’s business. But instead I have to check my Sent items each time to make sure I have a copy.
[update] This kinda seems to help
in the main window
open Tools->Message Filters
click “Filter Log”
Uncheck “Enable Filter Log”
then
Clear the log.
Hopefully it shouldn’t hang as much.
