Does anybody know why 6.0d runs slower on my machine, as compared with 6.0c? I've had to revert back to 6.0c....with no problems by the way. Otherwise, my computer boots slower (as does Vegas) and the playback of certain 5.1 projects freaks out my ASIO MBOX driver (whenever there's too many layered 5.1 tracks w/ lots of audio info)?
