Hi everyone

  First I would like to say a big thankyou for all your responses.  Um... I 
think on the basis of what you have all said that for now my safest option is 
to keep going with my licensed version of QT.  It is at the moment capable of 
doing all that I need.  In time I will contact GNU or Nokia to try and 
clarify what I can or cannot do, but for the moment I will run with my 
licensed version.  Any response I receive I will post on the list.  
  Again a big thankyou for everyones input.

Phil
