Last time I replied to a PM, it went to Outbox. I looked at it, and couldn't figure out how to get it out of the outbox, other than deleting it. Like who should I yell at? After a while I thought I'd give it some time, and maybe it'll just get sent somehow...
Tonight it's still there. And I replied to another PM; same thing.
Now I have 2 messages in the Outbox waiting to be sent. Did I miss the big red button?
