gtc954: If WBconfig says you need to reboot, it means that part of WindowBlinds is not installed correctly.
Did you get any error messages during install?
If you open regedit and look at these keys, do they exist?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\WBSrv
In most cases we believe this is caused by an application that is 'protecting' certain registry entries to stop apps from autostarting. While this can be a good thing, they need to prompt the user as during software installation you want to autostart things sometimes!
Additionally, if you have antiwpa.dll on your machine, this may be conflicting with WindowBlinds - as WindowBlinds will believe it is running in safe mode and so shutdown.
