That sounds like a really dumb question, I know... maybe it is... but scratching my head here. I accidentally deleted 1 message in a conversation thread. No problem, I'll just go to Trash - but it is not there! A search does not locate it either. How I did it... I open a grouping of msgs. (in conversation thread mode), highlight one of the messages in the pane above, highlight some text in the msg. text in the pane below, and hit the Delete key twice.
