I thought that maybe some new 64 bits machine came out and I don't know about this. Went to the beginning of this conversation and I am still not sure. Are there really some new 64 bits processor or, at least, something dramatically new about next 64 bits CPU? I have the impression that I wait for it for ever. Thanks, Leonid.
