Already tried that Opera re-install. No joy there either. Transferred across the network an identical lik from another Win2K machine and that wouldn't work. It does appear that Opera has opera(ted) on my registry. Contents of the link follows. Not sure what the "modified" is (i.e. it may refer to a key registry entry).
