I have found one improvement in 10.2.4 that is a big help to me. I am in the process of scanning slides at 4000dpi. The resulting jpegs are about 25mb. In 10.2.3, when I view the directory in the finder using icon mode everyting would almost freeze while bringing up the thumbnail pictures, and it brought them up excrutiatingly slow! I'm talking 5 minutes to view the directory with 30 images complete. I'm using an 800mhz iMac flat panel. After upgrading to 10.2.4, the icon directory view almost immediately gives me generic icons while it begins to load the real ones, and lets me be free to do other things, and it also loads the real thumbnails much faster than 10.2.3. By reducing the wait time, it has significantly cut down my trips to the fridge I make when I see the spinning rainbow wheel of death. Hence, I'm a healthier person. Geno
