Time Machine seems to work properly -- it has made many hourly backups. The only strange thing is that it has no background animation (starfield? Nebula?) just a white screen. I can see the windows scroll toward and away from me and I can see the UI at the bottom of the screen that says CANCEL and RESTORE. I also think there's a timeline on the right hand side, but it's very hard to see the light gray against the white. I know this isn't earth shaking, but it's very odd. Any thoughts?
