Probleme script Jquery animation

Bonjour,


J'ai récupéré un script permettant de mettre en place un slider en jquery
Mon probleme actuel est que la script construit une navigation avec un bouton "previous" et next"
Actuellement, quand on survol les boutons, cela fait animé les slide d'1 cran. Ce qui n'est pas tres intuitif en terme de navigation, car je dois sortir du survoul du bouton et revenir dessus pour faire continuer le slide (pas du tout intuitif)

Ce que je cherche a faire c'est au survol du bouton, l'animation avance d'un cran, on attends 300ms puis cela continu sur le slide suivant sans avoir a faire un mouseover, mouseout.

Une petite ame charritable pour m'aider ?
