Here is another strange problem. I restored a catalog from my old computer. I needed to move a few folders around (which I did in PSE10 Organizer). I deleted old folders from PSE10 that weren't in use anymore, but when I start the Organizer, it keeps showing folders that don't exist anymore with a few "ghost" thumbs that show no picture and have question on them indicating that the files aren't there anymore. No matter how many times I delete those files, new ones keep coming up each time I start PSE Organizer. Those folder don't exist on the computer. Any ideas? I tried Optimizing the catalog but it didn't solve the problem.
