Has anyone experience the installation of NW 6.5 SP3 overlay locking
while copying files in the final part of the install (GUI screen)

I have now re-downloaded and made 3 different SP3 overlay CDs which have
caused the probelm every time, so I believe the media is not the problem,
One of the CPU's goes to 100% utilisation while the other remains (near
enough) to idle., No Abend occurs.

Any tricks, thoughts or suggestions are appreciated
