Half of my screen is blank using Google Chrome. I can't see clearly email data (from, subject, date, etc). I tried expanding using the "View" tab, but all that does is open/close/move reading panes. The only sash I see is on the left. I need to expand my screen to the right.
Have you checked you history in Google Chrome browser and made sure there wasn't any. Also are you running ad block. I had to uncheck mine for one page other wise couldn't get things to load right. This morning had trouble loading pages with Chrome do emptied history. Shut down Chrome for a few minutes. Started Chrome back up and everything was good.
