We are a public library and own 5 laptops with 6 accounts and all of them are having the same problem with logging in automatically. 1 account is the instructors account and uses a non wireless, PC without Deep Freeze installed. This account works perfectly. I do not wish to want the children to have access to the account's passwords so the auto-login is a very useful thing. Ever since the last update we have been unable to let the children have co-op educational play and can only play offline alone. Please, please PLEASE help. Thank you.

2nd EDIT
Now with the newest version of the launcher once I disable Deep Freeze and login it works with Deep Freeze off. However, we need to have Deep Freeze installed on these laptops as they are handed to very young children and they can get into trouble with computers. Being able to keep the laptops safe and useable for all our young patrons is important.
