This has been a recurring problem. My finder is slower than it should be in responding. I'll click on a folder or a file and it will take 1-2 seconds not instantaneous like it should be and it lags when I try to click and drag a folder or file. Then my fans slowly kick on and cpu level spikes for a moment. The only way to remedy the problem is to restart the computer and then it's okay until I hop on the next day which I leave it on over night. Is there an exact culprit for this issue? I'm running 10.6.8
