Did an archive and install from Tiger, and now cover flow previews are low-res and blurry, presumably from the thumbnails in Tiger. Question is, how can I tell Leopard to redraw the thumbnails from scratch?? Anyone know? EDIT: Yes, I can force a redraw ONE-BY-ONE by opening Info and deleting the icon, so how can I automate this? before: after: K, how to automate this??
