The mail messages and news group messages do not display at all using the last 3 nightly builds on WindowsXP. The folder window displays its information correctly, including the number of unread messages. However, the list of messages in the right window, as well as the preview pane, are empty. Curiously, the scroll bar in the message window does activate on those folders that normally trigger the scroll bar. Everything work ok if I backrev to the Oct 11th build.

What columns do you have *hidden* in your thread-pane?

Probably a dupe of bug 108579. Mike, could you check if adding the Thread column makes your messages reappear, and mark this as a dupe?
