taojones I don't know about that. By go to sleep you mean not just the monitor but a complete wind down of your Hard disk drive also? Your HDD would most likely need to be active to continue writing files to the drive. It's one or the other. Sleep may also affect your net connection!

By the way, the LW program can a type of sleep function itself. If your comp has been left inactive for a considerable period, LW will slow itself down. But it will continue downlding! Search SBerlin's posts about this topic.
