Is there any way I can resolve this so that it makes effecient use of all four cores? I'm running an Intel Core 2 Quad Q6600. Thanks, Michael. ID: 706577 ·

You were running on 4 cores, so I am assuming that your Seti preferences are set to allow 4 or more cores. If you launch task manager does it show 4 cores or just 1?

Click on view, CPU History and make sure it is set to "one graph per cpu". That will make it show all 4 graphs. If it's set to "one graph, all CPU's", you only see one graph and it looks like a single core system. ID: 707065 ·
