I used TinkerTool for a while, then I deleted it. But all of its settings are still effective, what should I do?
As mentioned above, TinkerTool just changes user preference settings of Mac OS X. Applications will respect their settings no matter if TinkerTool is on your disk or not. If you want to reset your configuration, just open the Reset pane in TinkerTool, choose one of the reset buttons, log out and log in.
