When I double click on a video file icon the dock moves as if an application is about to open but then it returns to normal. I can't get my video files to play. I have to open up movist by itself and then select the file from the menu to play it. How can I fix it so I don't have to do such a thing? I already tried reinstalling Movist. I also restarted the computer. Both didn't work. I must say macs are pretty buggy.
