I don't know what happend but the diagram grid proportions are different they're not the same they used to and also I can't align perfectly the elements it's bothering me. I use this tool because a can put in perfect place the elements and now I can't. I tried to adjust it but it didn't work.
I like this tool because it meets my perfectionism necessities and it's pretty easy to use but now I came across with this unexpected issue and it's giving me a little of a hard time the change is so sudden that I can't cope with it.
