Hi,
For some reason, I cannot create new polygons except for very simple ones (triangles, rectangles etc...)
The vertices simply do not add when I click to add them, or whenever they do add, they disappear after I advance to the next vertices, and lastly, I often either can't close the sketch, or most of it is closed but some of the vertices get left behind.
Has anybody encountered this problem?
It happened to me while adding a new shp of polygons, but now it remains if I try to make new polygons of already-existing shps of polygons
