Computer Locked After Power Save

Only after my computer has gone into Power Save Mode (not screen saver), I'll get a message coming out of Power Save Mode that says: 'Unlock Computer. This Computer Is In Use And Has Been Locked. Username:______, Password:_______'.
I'm the administrator with no other users and have not set a password for anything. When the above message comes on, all I have to do is hit enter and everything is OK.
I've right-clicked on Desktop-Properties-Screen Saver-Power-Advanced and unchecked the box that says: 'PromptFor Password When Computer Resumes From Standby'.
Thanks in advance,
Bruce

 

I found this for Windows 2000....I wonder if it would still be applicable?
