I have been having this issue for the past week and it's driving me nuts. Let me start by saying I don't use the "message pane", I don't like it. I have my emails listed as they are in the attached pic. I don't know what changed but before when a new message would come in it would be in BOLD and once I clicked on it to open it in a new tab it would automatically mark as "read" (or un-bold). Now when they come through they are not in BOLD and since I get so many, and am not able to save or move them right away, I get confused as to which ones I have actually opened. Right now I do NOT have the box checked to "automatically mark messages as read" so one would think this would mean they would stay 'un-read' until I open them but they don't. Yes, I tried to click "automatically mark message as read - immediately on display" AND "automatically mark message as read - after ?? seconds" - - the first does what it's doing now, doesn't show them BOLD - - the second will show them as bold for exactly so many seconds and then un-bolds after that time which still doesn't help because I may not check my email for hours at a time. I hope I'm explaining this ok ...... the bottom line is I need for my emails to stay BOLD until I either read them or mark them as "read" manually.
