More than once, the contents of my message pane has suddenly gone blank. one minute I was viewing each email in the message pane beside it like normal, the next minute, the message pane was blank. From one time to the next, I can't remember how I restored it. It just happened again. I tried restarting (which I believe worked in the past) but no luck. I think what caused the problem this time -- and possibly last time too -- is clicking on a link in a particular message from a specific sender, linking to a document found inside a password-protected portal. I just want my message pane back! (and to prevent this from happening again if possible). What do I need to do?
