Hi, This problem partly began with the update to 91.2.0 and has changed somewhat with 91.3.0 91.2.0 Pressing send button or ctrl-enter + enter *erratically* results in the message being sent or the message not being sent (and the compose window remaining open). Pressing send one or more further times eventually results in the message being sent. I have seen no discernible pattern about what triggers a successful send. 91.3.0 The frequency of the not-really-sending behavior has decreased, but it still occurs on occasion. In addition, after every *successful* send, I get the following error message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) XXXXX.XXXXX.com timed out. Try again." [Xs added by me] Yet the message sends (so the error is wrong - I can check via the web interface for my email server), and the message is copied to the Sent folder as it is supposed to. Any ideas on what could be causing this?
