--- Comment #5 from Jan Vlug jan.public@famvlug.nl --- Sorry for my late reply. The interesting thing is that the flickering did not occur any more since comment 4 was added. I was waiting for the flickering to occur again before posting the requested info, but it did not until now, so I will attach the requested info while the flickering is not manifest.
