Hi Pilou,

Yes you make one selection per corner area, but going starting from the left and going to the right. When you go in that direction it only captures things that are totally contained inside the window. The other direction (starting right and going towards the left) which you are showing above will capture anything that crosses the box at all, which you don't want in this particular case.

Here is a demonstration, especially notice the on which side I start each window, and see how quickly it goes:
