I had tried to copy some files off a flash drive, and I accidently ejected the drive before my files had finished copying. And since then, the copy window has been stuck open at 3.32/3.5 gigs with about 10 seconds left...and I can't get it to stop copying, or restart, or do anything to make it go away. When I try to restart it just says finder can't close because stuff is running. How do I fix this?
