Response to request for more information
Thank you for your response to my query. The reason I have taken so long to reply is that since posting my query for help the VCD application icon has steadfastly worked correctly every time, so I have been unable to provide any additional information to help you diagnose the fault (if any). I don't understand it. It consistently failed the way I described up to the point of requesting your help. In the circumstances, there doesn't seem any point in continuing with this task so I am happy to let the matter drop, at least for the time being. Thank you for your interest nevertheless. Alan
