Problems copying files in Lion?
I'm having some strange issues copying files in Lion on a fresh install. I drag files from one drive to another, and the files seem to copy- the progress dialog comes up, the "ghost" files show up in the destination window, the copying takes about as long as one would expect for the file size, but upon ending, nothing... the file disappears from the destination. This has happened both on a USB external hard drive and on my NAS which is hooked up via Gigabit Ethernet. Copying via cp in Terminal works just fine, though. Any ideas?
