Hi Fabio,

After thinking a little bit more on the problem and speaking with my colleague (whos form this one is), I think we would put a shape on that container. Since button click's call common method, we would just operate this shape's coordinates and visibility.

In other words, instead of a new class we would deal with the problem in the particular form's instance.
