I am running Lion off of an Intel 320 SSD, which replaced my optical drive. When I try and open up a movie from my downloads or from one of my external drives, it takes a few seconds to load. The same thing happens if I want to open up a picture I have on my desktop. For example, I opened up a picture, the Preview app would bounce up and down in the dock for about five seconds, then it would open up. Any thoughts?
