I accidentally used an old Leopard Dock application to attempt to change my Dock skin, and it screwed everything up. I borrowed another Mac and copied the Dock app from Core Services and replaced mine, but there's a white line across the bottom of the dock still. http://i127.photobucket.com/albums/p126/burlyman007/Screenshot2009-09-02at111532PM.png I know I shouldn't have been messing with it in the first place, I KNEW things had changed between Leopard and Snow Leopard, but I did anyway, and now I don't know what to do... It really bothers me! If anyone could help it would be greatly appreciated.
