I understand that Civ IV is hungry for memory. But is there some way to avoid some of the obnoxious side effects? 1. I would like to be able to listen to streaming audio (like Air America Radio) while playing. But as time goes on, Civ begins to impede the audio feed and it eventually breaks off. 2. After exiting a Civ game, it seems to not have released its memory resources, so I have to wait a couple of minutes to run something else. 3. After breaking out with Alt-TAB, it seems to take forever to resume.
