Hi, I have a bunch of movie trailers in a stack on my dock. Every so often when I click on a movie trailer, the video won't appear on the screen for about 10 seconds or longer. It's as if I hadn't click on the trailer to play. Once the video appears I can play it without a problem. Then every trailer that I play after that, opens immediately. Is this normal? Anyone else have this happen to them? I have repaired permissions several times. Any help is greatly appreciated
