   Hi Ed,   
      
   EV> EV> P.S. I was in a Goodwill Store yesterday and paid $1.00 (US) for a IDG   
   EV> EV> book called "Windows NT 4.0 MCSE (Microsoft Certified Systems Engineer)   
   EV> EV> Study Guide" by Alan R. Carter, that had an Unused CD-ROM disk in the   
   EV> EV> back of it with the Text of the book in .PDF on it.   
      
   How could you determine that the CD was unused? If somebody had read the   
   PDF-file it wouldn't have a sign on it saying it had been read.   
      
   It must have been used to record that text on it. You can't record a CD   
   without using it, hi.
