After having saved my data files I exited Paradox 10. When I attempted to log off Windows 2000 Professional there was no apparent response. The Task manager showed no applications running; none were therefore 'Not Responding". I then attempted to restart Paradox and was informed that the BDE was busy. Ultimately, I rebooted by pressing the power button whereupon all applications opened and closed successfully except Paradox. It exhibited the same symptoms.
