Copy stopped

[Aranince]

I am trying to copy my iTunes directory from my NAS to my new macbook. During the file transfer an error popped up saying that it could not copy a file because an error occurred. So I clicked okay, and the copy window is still open, but has not changed neither time nor mb transfered has changed in the time of a few minuts. I still can navigate the NAS and still have network connection. How do I stop the copy so I can retry it?

Ok, fix is command-option-esc and kill the finder task.
