No prompt for password coming

I’m having a strange problem. Prevoiusly I was working with version 6.0.2. I newly installed Notes 6.5 and now without prompting for the password it’s enetring into Lotus Notes.As a result Anybody siiting in my computer can access my mail file.

Can anyone suggest what might have gone wrong.

Thanks in Advance

It enabled by an install option. To disable it go to File / Security / User security. Uncheck the box "Login using operating system login>

Thanks Mr. Bruce,

The information you gave was just fine, but the option which you wanted me to uncheck under Secuirity-> User Secuirity is disabled.

Please advise how to enable that option and thanks in advance
