bhx...I didn't search the net-had come up empty handed when I did that before, but I did hover the mouse over the driver file that was not copied. And it resulted in the name of the little program I'd downloaded that the file belonged to. It was Cyberhawk and it is a small automatic virus/spyware (free) detecting program using behavioral analysis instead of virus signatuares. I use it supplementally.

Well, what to do was obvious--close Cyberhawk and try copying again. No problem.

Your suggestion got me on the right track--that I should have been on anyway. Thanks!!
