Hello, My System Preferences app doesn't open. It's missing from my Applications folder, it isn't in my dock, and when I try to open it from the menu it doesn't open at all. I have tried repairing permissions and everything on the 'net. I do not have my Mac install discs with me, as I'm not at home and won't be for a long while. I need a copy of someone's System Preferences.app (he must be running 10.5.8, I believe). Just .zipping it, uploading it on DropBox and giving me the download link would mean the world for me! Thanks!
