This is starting to get annoying now. I am the only user of my MBA, but when I try to install flash or flip4mac, it asks for my password. I thought "All right, I will enter it", and for the past two months it works just fine. But starting last week, it doesn't recognize my password anymore. I use the "verify permission" in disc utility to no avail. The password is the same as the login password, and the login works. So I don't know what the deal is. Can anyone enlighten me please? Or just show me how to turn off this password protection thing until I get a better grasp of what it does. Thanks.
