Whenever I first boot, things are ok, but after an hour or more, the desktop seems to become stagnant and doesn't update. I can't highlight anything on the desktop visibly, but it DOES highlight it in the background, just no visual confirmation of success. New icons of saved files to my desktop do not show up. Dragging icons to a new location shows a ghosted icon as I drag, but the original stays where it started and after I let go it gets snapped to the grid in it's new location, but is invisible. I can click on the invisible icon and it works, and the original location of the shortcut no longer works. So it IS moving the file, but it's just not updating the desktop layout, etc. Once in a while, if I hold down the windows key and press D (desktop) it will minimize my windows and the desktop will refresh and come back to life for a bit, but usually even that doesn't work.
