Both 9.xx and 10.xx versions of Opera are re-requesting proxy auth after the browser restarts. The login and password inputs are already filled in so I need just click OK button but I need to do this for every tab a few times.

How can I stop it? In internet Explorer and Firefox everything is fine.

Opera seems to have a problem with NTLM (Windows authentication) proxy servers.

This seems to be a common workaround: NTLMAPS
And it's described here.

NTLMAPS is a little proxy server which you run on your PC; it sits between Opera (once you configure Opera to use it) and your Windows auth proxy server, and handles the NTLM authentication which Opera cannot yet do.
