hi all. so my 12"pb has a new problem. seems that finder is continuously beachballing. things will work fine until i open a finder window to say select a file. after it opens, finder always beachballs and is non-responsive. after maybe 3-5 minutes the beachball goes away and i can click for a few seconds then it beachballs again. ever see this or know what's going on? i'm running 10.4.9. thanks.
