Have my Inbox selected in Folder List view. I go to Standard toolbar View / Arrange by /have Date selected and everything else turn off. Not sure what I did? I was seeing the Arrange By: Date field in my column header field, now it is gone. Before I adjusted the Vertical Spilt Bar and pending the windows sizes I would see the Arrange by field and not see the arrange by field. Now it is total gone. What causes that? I do I turn in on and off??
