I am a law student and my school uses the Outlook Web App for our email services. I am unable to scroll upward using two fingers on the trackpad of my macbook air in my inbox list of messages. I am using Google Chrome. This is not only a nuisance, but a semi-serious problem, as if I reach the bottom I can not scroll to show the scrollbar and drag it upward which is my only makeshift solution, and must refresh. How can I resolve this?
