So, after upgrading to Leopard, I noticed that I have two copies of "calculator.app" one in applications/utilities, and one applications. Of course I deleted one - the wrong one. When I tried to open the one that I kept, it said that it couldn't be opened in this version of OSX (yes, i emptied my trash, too). Anyways, does anyone know where I can download the default Leopard calculator.app? Thanks!
