Ah! Thanks I hadn't noticed the tray icon.
I downloaded a couple of the other programs and tried compressing my registry.
when it starts compressing I get a dialog box with message "C:windows\System32\Config\System is Corrupt"
Any idea what to do about that?
I rebooted and tried it again and still get the same message..... I haven't noticed any problems so far.
thanks for your help
Mike
