Does anyone have this issue that I am experiencing where it seems like everything I do on my mb pro gives a slight hesitation before it completes the task? It could be something as simple as scrolling down, it will wait a second and then start scrolling. Or when I am watching a video, the video will freeze just for a half second, every 5-10 seconds. I have installed Lion and was experiencing this annoying hiccup, so I did a clean install and installed again and I still experience it now and again. Could this have something to do with the Spotlight?
