Can anyone help, I have managed to delete my calculator. I have an iMac and it runs on OS x 10.2. I have tried reinstalling the software, but to no avail. I had a look at 'Restore' and that is pretty scarry. The thought of losing everything on my computer is not an option, I haven't got any of it backed up. I know it's possible but don't know how, unlike with a PC you cant look at the directory of a disk, or can you?
