well, cdbrown, you're turning out to be a very helpfull guy!
found exactly what i was looking for, windows now just displays a login box for a split second, the goes straight into MAMEwah. when you shutdown you see a logoff box (again, for only a split second) then shuts down
GREAT!
here's how to do it (if anyone else need it):
1. click on "Start" - then click on "Run" - and type
"control userpasswords2"
2. click OK
3. On the Users tab, clear the "Users must enter a user name and password to use this computer" check box and click "Apply".
4. A dialog will appear that asks you what user name and password should be used to logon automatically, just click "OK".
Then go to Control Panel / User Accounts, and click
