Finder shows sizes greyed out and folders empty In Lion, Finder shows sizes greyed out and when I open folders, they seem empty.

Upon "Get Info": they also look full with normal sized files.

WHy? How do I fix this?
As best as I can tell, the file sizes are greyed out while Finder works to calculate the current size of the folder.  If you wait a moment and let Finder works its magic, you'll see the file sizes appear in the usual black font.
