Hi Hbasm - another way I might describe it is that each curve in the Network should be like one longitude or latitude line.
When you have a little square curve, it is like a portion of a longitude/latitude line instead of a full line - you need to make curves that are like full long/lat lines instead.
The little square region will be formed by the intersection of the full lines, not something you actually explicitly draw as a little region itself.
