"Call was rejected by Callee" message

  Q.    When trying to export an Options Pattern to an Excel file, I got this message:
Error message = Call was rejected by Callee

  A.   The cause is usually that Excel is "busy" at the time the program is writing to it ... perhaps because you are accessing another PC on a network, or because you are working manually in Excel at the same time?
It seems to be an occasional thing - so if you try again later, it will probably work OK. 
Alternatively, select Export to CSV ...and then load this file into Excel.
