Hi again, Davide, I think we are having some language difficulties. The reason I asked you about private browsing windows was to have you try using one. It's a diagnostic step, to help rule out any browser extension conflicts. If the game works properly when using a private browsing window, then we know that it is a browser issue that needs to be solved, most likely an extension. Also, when you say "i cannot drag nothing from the library, nothing show up." do you mean that there is no image in the library, or that when you drag the image from the library it does not display in the play area?
