Mountain Lion 10.8.2 with MailTags.

If I select text it works fine. However, expected behaviour if I have clicked in the mail message but not selected text would be to copy the whole message.

If the last click was in the pane listing the messages, it attempts to copy the whole thread. But it doesn't work properly.

For example, if the thread looks like this:

2nd reply from me
Reply from sender
1st reply from me
Original email

What gets copied is:

Original email
