I’m using Outlook 2010 on a Win 7 64-bit system with the reading pane located at the bottom of the page. Sometimes when I single click on a message, it will expand to full size as if I had double clicked it, which is not what I want it to do. Similarly when I try to close that message by clicking on the X button in the upper right hand corner, it will occasionally completely shut down Outlook requiring me to open it again from the beginning. However, this process is totally random and I have no idea what to expect each time I perform this task.
I’ve already done a Repair of the entire MS Office Professional under Programs in the Control Panel, but that hasn’t helped it at all. Is there anything else you can think of to suppress this misbehavior?
