OWAS-How start a new session without to close the browser?

Hi!

I have a problem with OWAS.
I have OWAS 3.0 installed in NT 4.0, the authentication schemes is "Basic-Oracle" and BD is Oracle 7.
When you connect and stay idle, if idle time exceeds the time specified in "Max session idle time - Cartridge" you need starts a new session. How do you connect again?
How you cannot autenticate again in BD without having to close the browser?
How you can alter the password in BD and in your browser session, through a form?

Thanks in advance.
