I have windows XP Pro (version 2002) SP3. When I lock my computer, I do not see the "Computer Locked . . . " dialog. Instead, I only see the "Unlock Computer" dialog immediately upon locking. I am concerned about not pressing Ctrl+Atl+Del before entering my password to unlock. Is there a setting that I can change (I have extensive knowledge of windows registry and system tools, but I have not been able to find an option to "Show only unlock screen".
