AFAIK & I'm definitely no windows expert here, but... If you're using more than one LW at one time then it would not be possible to utilise the same preferences at the same time. If you attempted to do I suspect you 'might' end up with corrupt downld preferences. But then I don't know. I'm purely surmising! Why not instead, have separate user accounts for each one, & save them to separate folders on the one computer. At least have separate save folders for that one comp you want to save to. (I could be wrong about the references as sometimes people have had more than one LW running from one comp.)
