My dock accidently went transparent like this one before I had even heard of Dockulicious. I had to restart my computer for an update and it went away. I was sad. I looked through the discussions on the Apple web site and apparently people didn't like the fact that it went transparent on them. I love it! So since it's not supposed to do that, I'm really glad I found this site and your dock. However, I think it would be perfect if the open application indicator was the little blue sphere that comes with Leopard and not the black circle that you've made. I hope this helps. Thanks!
