This is a problem common to both v2 and v3. Sometimes I'll try send a message to someone I've never written to before. In v3, I click 'Send,' the green checkmark appears (perhaps signalling that the message has been sent), the message dialog box fades out, but when I check my Sent messages folder, the message is not there. I never hear from these people, so I assume that the message didn't go through. I used to try a second or even third time, but the same thing happens. It's as if the messages just disappear.
