A few files that are lying around from some old application demo that i deleted are inside the demo application, and is refusing to empty from the trash, because it says it is locked. When i open up the application, the files are locked, but when i go to the info pane, i cant uncheck the locked box because it is disabled. So i go to the permissions/ownership part of the info pane, and i unlock it and change it to my permission, but an error comes up, so i can't unlock it. Pain in the ass. Help, anyone?
