My case was closed because the person who saw it thought that my problem was that i could not see the grid, but that wasn't my problem and as you can see in the title, my problem is with the tool of grid alignment. When i use it, it is suposed that i can see a translucid yellow square to help me align the grid of my map correctly so i don't miss it, instead it appears absolutely nothing, so please if it is posible ask me before closing my problem if the problem was solved, but first try to solve it please. I tried in several computers so or im the person with bad luck or it's a problem of the page.
