Ok, totally purged all mail prefs, mboxs, etc
On a clean copy of mail i set up 2 accounts, 1 .mac, the other from my ISP.
I send a mail, then reply. As long as I leave the message in the Inbox, i can view the my reply. If I move it to a folder On My Mac, busted.
I did the same thing again, but this time made a rule to place the message in Folder upon first receipt. I send a reply from within a folder....busted... can't view.
Is this only me?
So much for a useful feature. Disappointed.
