In the past, if I wanted to view a particular e-mail in the bottom pane, I would use my mouse and left click on it to select it.   Today, however, I cannot use the mouse to click on any message.  Only the top message remains selected.  The only way I can get to choose any item below it is to use the down arrow.  This never happened before.  Has Outlook been changed so we have to use the arrows to go from message to message?  It is a real pain in the neck.
