After years of creating viewports with drawn rectangles, all of a sudden on files I've been using for a long time, a green rectangle comes up in 2D crop viewports both on the sheet layer and the original design layer. Sometimes there are several stacked on the design layer. They show up as simple rectangles in the None class - I can delete them, but they come back. I've never seen these in over 17 years of using MiniCad / VW. There must be some default that got triggered. I'd like to know how to get rid of these for good. thanks, Ken
