Sono intenzionato a fare un testo scorrevole verticale che si blocchi al passaggio del mouse e che scorra quando il mouse si toglie. Inoltre vorrei che si attivasse all' inizio. Ho usato questo script, preso da Html.it e l' ho modificato, ma ho un solo problema: appena finisce di scorrere tutto il testo si blocca completamente e non ricomincia più. potete consigliarmi qualche script dello scorrimento (magari non in Java) o dirmi cosa aggiungere in questo, per favore?
