Thank you very much Corinna.  I will definitely try that out.  The
machine in question, unfortunately, had been pulled out and I would
have access to it only in the next week or two.  Hence, my updates
regarding this topic would come a little bit later.  I am, however,
interested in a resolution, if there is any.  Thanks to all you've
suggested.

Until then.

Best Regards,

Carlo
