The screen is split down the middle—my email is on the right side and Google Chrome is on the left. Everything worked perfectly...I just couldn’t get a full screen when browsing! Or...looking at my mail, too!! This isn’t about ‘panels’ in the email...it’s about 2 apps on one screen!! Fortunately, I fixed mine!! I finally noticed a ‘handle’ or a small silver thing, in the small space separating the two halves of the screen—it looked like a ‘slider’—something you would tap & slide up & down. I began screwing around with it and Eureka! It went back to normal again!! So...maybe someone can look into that...I have no idea what I accidentally did in the first place to get it split. But I’m glad it’s fixed now!!
Thanks for your interest in helping me with this issue! —Jude—
