Just noticing recently after my Leopard drive died and I am back to Tiger... why is the Leopard dock so choppy compared to previous OS's's? I have never met a Leopard dock as smooth as a Tiger dock, on any system. I manage a lot of systems, and have noticed that, without fail, the smoothest, most buttery dock is on the eMacs, running Tiger. Much smoother than Power Macs or Mac Pros. Strange indeed.
