A bit more information on that last post. I have not intentionally been fiddling with the Registry. The only thing I have done is a registry cleanup with RegCleaner - JV powertools - but have done this regularly with no ill effect and certainly never had this message before. Thanks, Sandy :) ----- Original Message ----- From: Sandy O'Neill To: triadtechtalk@xxxxxxxxxxxxx Sent: Monday, December 08, 2003 9:45 PM Subject: [triadtechtalk] RegOpenKeyEx Hi Everyone If I click on Properties on any of my C D or F drive, I get the message "RegOpenKeyEx: The handle is Invalid". Can you please tell me what this means.... I have no idea how I have got it. I then press OK and it shows the properties normally. Thanks Sandy :)
