This news is two days old, but I've not founded time before to say thanks Tom. Grabbed from here:"Leopard’s Finder has a glaring bug in its directory-moving code, leading to horrendous data loss if a destination volume disappears while a move operation is in action. I first came across it when Samba crashed while I was moving a directory from my desktop over to a Samba mount on my FreeBSD server." Here we go, it's time to Leopard's bugs ! Really Good personal working stuff. Here there is also an avi for people don't like read.
