I used to tap the space bar and preview tons of downloaded flash video on my mac offline with the quick look function in a folder. Now, since I've upgraded to Lion I no longer can click the space bare to use preview in a folder to view a quick flash video. I know I can use VLC, but I have a ton of flash video's and want to be able to quickly preview them and scroll through them. This was no problem on Snow Leopard. Did Apple pull this from Lion? What am I doing wrong? What setting do I need to fix?
