Hello I am using an Intel based iMac 2.8GHz, has 4GB memory, OS 10.5.6. It has 16GB Hard disk free. After finder has been up for 20 seconds or so the response time between clicks gets really slow (1 or 2 minutes). The problem repeats every time Finder is restarted. When I look at the Activity monitor the Finder shows that it is taking up 840MB of RAM and most of the CPU. I have repaired permissions and that helped for a short time. Thanks for any suggestions!
