Hi everyone I'm back. Last time I spent quite some time complaining about how Silverfast would lock your machine if you had anything on your PC IDE controllers other than Hard disk drives and CD ROMs. So its time to redress the balance. I would like to congratulate them on fixing the problem. At least I think they have, but as I have a somewhat different PC as well as a new version of Silverfast I can only be sure if I reinstall the other version . Anyway I am a happy punter, Silverfast works and works well. Steve
