Good Morning, Thanks, Robert, I knew it should have been something simple like that. I discovered it by accident while comparing the code between 2.9.16 and 3.0.1 and now the viewers are all responsive with the ON_DEMAND flag. The help is much appreciated from everyone and I am glad, Andre, that you have come right too.
