I finally got my 27-inch iMac today and the first two things I decided to do were install Guild Wars 2 and copy data from my external drive. I minimized the GW2 installer and noticed that I could still see it on the desktop. I moved the copy status out of the way and could still see it as well. Is anyone else having this problem? I don't want to go through what others have with the Retina MBP. I believe all of the iMacs are using LG panels, so I'm not sure if it is worth exchanging over. ---------- After typing this post, I closed the forum window. You don't even want to know what it looks like. Ugh!
