Thanks man i used the second method.
How about the dock? We used to be able to drag any application in the dock out, now i tried the command+drag, this don't work for dock. Any idea?
For any icon on the Dock, just drag it away from the Dock and hold it there for a second or two before letting go. It will remove it from the Dock. Of course, this won't work on an app that's currently running. Quit the app, then do the above.
