Hi Nick,
Do you mean delete any default displays and then run it? I did that, and no
error messages wrre throen, although the programme did go unresponsive at
about tick count 674.0. I had to stop the thread from the console as the
pause or stop buttons did not work at this point.
Kind regards,
Erica.
