Well, 1024 is the maximum resolution on this monitor. As justheretotakenotes observed, this suddenly makes using the "new post" option a total chore, scrolling up and down the screen all the time. I've managed 480-odd posts in two and a half years without ever once thinking "Gee, being able to use the preview/schedule/category buttons on the same screen as the text, title and excerpt is really bad."
GIVE US THE OPTION TO TURN THIS OFF PLEASE.
