I have a user who uses this feature frequently during the day. Lately, when he manually locks the computer, the screen appears to be blank except for his
wallpaper. He cannot use CTRL+ALT+DEL to bring up logon screen and has to do a hard shutdown to regain access to his computer. If the computer locks on it's own with the "screensaver" feature, the logon screen appears and
computer is fine.
The OS is WinXP w/SP2. Any ideas how to resolve this issue? He wants to be able to lock his computer whenever he steps away.
