Hi I am an autocad user who is trying out Draftsight. There seems to be "default" viewport on the layout sheets. Even if you add a new sheet or create a new sheet this "viewport" is there. You can't see it until you double click within it. There are no grips or an outline of it to simply delete it. I'm thinking it's not really a viewport at all but am not sure of how to get rid of it. Please help. This is very frustrating. Thanks
