Hi David,
Passwords are stored in the registry in HKEY_CURRENT_USER\Software\Four Js\Genero Desktop Client\Monitor\Passwords. Of course they're encrypted.
Now I'm not sure to entirely understand your problem: indeed when you type a wrong password, the password field will not be pre-filled the next time you attempt to connect, but as soon as you type again the correct password, it will be filled again
Could you a little bit clarify how does it work in your environment? BTW, what is the GDC version you're using?
Thank you in advance.
Best regards,
Lionel
