i'm just wondering about how Panther uses the RAM, compared to Jaguar. does Panther store heaps of stuff in RAM? like with Jaguar if you had a app open, it would be best just to leave it open, or else it might reload all the stuff into RAM again. does Panther behave like this? a situation where this might apply... the new System Preferences. in Jag, you could close the window, but the app would stay open. now in 10.3, you close the window, the app quits. so is it better to just hide System Preferences in 10.3? if you quit it, then start it again, will it reload data into RAM?
