Ah, I do see "mDNSResponder" in the Task Manager. It's tiny though (like 3k), but I wouldn't have known it was from Apple. Thanks for that info.

I just got back from the computer store and now have 2 gig of working RAM in my system. CS3 still lags just like before, so that wasn't the problem.   :(    I guess there are just two more things to wonder about: what Thundering said about telling Photoshop that I have a dual-core system (how?) and could the fact that I'm running it on a 37" 1920x1080 widescreen monitor have anything to do with the lag?

Thanks very much in advance and for the advice so far.
