For NTLM authentication, a authentication password dialog box will be popup for user to enter info in order to pass NTLM:
Username:
Password:
Domain:

There is an check box in this dialog box: Save the password in your password list.

If user check this box, the information in the password dialog box will be remembered and user won't see this pop up password dialog box next time when he access the same URL.

User click on "OK" button, the password dialog box should go away and applet should wrong.

Well, in Mustang B88, if user check the above box, the password dialog box will be popup again and applet doesn't wrong. If user don't check the box, it works fine.
