Logout not fully working right.

I have this login form that goes to the application.cfc to make sure the user is in the DB then allows the user to continue to the folder according to the users access privileges. The login works fine and all, but if you hit "logout" which goes to a <cflogout> file and logs the user out as you would except. Here's when the problem begins. When you go to the login screen again WITHOUT closing the browser i can enter anything in the login for and it will log me in. So  now the cfc file won't recheck the login information given and allows me to go straight to the folder which i DO NOT want people to view unless the are allowed to.

I have tried to clear the session and the cookies in the browser. One thing i should add is that IF i fully close the browser it will do the login verification again if i launch the login form. I will admit that this is new to me, so any help would be great.

I hope i given everything needed to see my problem and that i have explained it enough.
