On a brand new 6.0.2NE install I'm experiencing a weird problem. I cannot display a message in a thread.
I have a thread of 3 mails, and one of them is not displayed. I can see the first, the last, but not the middle one. When I click on it, the preview pane remains blank. If I double click nothing happens.
This happens on the standard ajax view. Using HTML interface, or imap, message is correctly visible.
I've tailed mailbox.log, but no exception was thrown.
what could it be?
