Hi all, right now I have the Leopard OS installed on my macbook pro, it was an upgrade from tiger. The thing I want to know is that if I downgraded back to the Tiger OS (yes why would someone do that), would all my programs still be there? I am talking about programs like Microsoft Word/Excel/Powerpoint. I can't install these again because they came with the laptop when I bought it. So I really need to know. Thank You for your help.
