I don't want to make an "up", only give a proper title to the post.
In the note's pop-up window over the text entities are visible.
Version 3.3 and 4.1 works well to me, but with 4.0 and 4.2 I had that problem.
When changing versions, it's better to overwrite or erase before install?
If it's not an incompatibility with 3.0.1 (to me, was the same with 2.9), what could it be?
