After upgrading to Leopard, when I try to install or update any program on my computer it asks for the Administrator username and password. Well that should not be a problem seeing as how I am the administrator and so I type in my name and my password and it says "you must type an administrator's name and password to make changes to software update." So I went to system settings and checked and it no longer has my account as the administrator and I can't make any changes because I am not the administrator no more. After installing Leopard, this has happened. What should I do? (I am fairly new to Macs, I have had my Macbook about 3 months.) Another note: I also noticed that my Macbook (when I shut it) has started to wake itself up from sleep mode and stay that way while it's still closed!
