Thanks again for swift replies. You guys are really quick. Yes BOTH machienes (there are two, but one has dual boot,) are patched to the same version, but it is probably not the latest version. Thanks for the info on the processors. Is that correct? Wouldn't the host compensate for slower players? Anyway, the host uses an Athlon 1.53Gh and the client uses a PentiumIII, so the difference is quite substantial, both in clockpseed and processor architecture.
