Mr.Dan, mine did not "freak out" but I turned it on from completely powered off last night and there was a forth tile row. I had previously read this thread and thought maybe Microsoft had made it work or something and I just had to reboot the surface to make it happen. I was loving it! Later on I woke it from sleep and the 4rth row was gone. I was totally bummed as the forth row looked great and meant I had to scroll less. Has anyone else seen this on theirs or can provide a reason why it may have happened? Also, Mr Dan does yours still have 4 rows?
