When I attempt to compose, reply to or forward an email, the window that opens up is very small and cannot be explanded. I'll click the little diagonal arrows to try to expand but it doesn't do a thing. I used to get a full window.
NOTE: This issue has been resolved. I found that if I ZOOM in to enlarge the view, that it solves the problem. You can also hold down the ctrl button and rotate the wheel on your mouse to enlarge the view to correct the problem I originally wrote about.
