In a previous (unreleased) version there was a problem with the device
stopping and starting - it would occasionally fail to stop the network
adapter because it thought there were packets still to be sent or
something. I thought I'd fixed that problem but it was occasional enough
that it was hard to be sure that it was really fixed. I haven't seen it
since though.

Is it happening every time?

Copyconfig only mucks around in the registry. It doesn't stop or start
any adapters. It has to be run with the qemu device present though I
think.
