I looked in /Users and tried that name. Didn't work. What has happened is the other day the computer would not boot. I ended up having to reinstall 10.5. I can't remember if I have installed anything since I did this. Tonight I did the new security update. When it came to installing you get a window showing your admin name and asking for the password. Tonight the admin name was blank. I tried using the user name in the home folder and my normal password and if failed. This password has always worked up till now. I then went to system prefs/ account and tried that name. It failed. I even tried Admin and Administrator. I booted off of the CD and had reset the password and that didn't help. If I go to sys prefs/accounts it does show me as a standard. I then tried to change my account from standard to having admin status but it then asks me for Admin name and password. Last case would be to reformat the drive but would like to try other options first.
