Spry menu chevauchement avec IE

Bonsoir,

J'ai de nouveau besoins de vos lumières !

J'ai intégré via dreamweaver CS4 une barre de menu spry horizontale qui fonctionne très bien sous Mozilla/Chrome. La page est en .html.
Le souci se pose avec Internet Explorer. Les sous-menus apparaissent bien mais se placent sur la barre de menu. Tout allait bien au départ jusqu'à ce que je change la police. Mais même en revenant à l'ancienne police le problème persiste.

Merci de votre aide,

Ci-dessous le css de la barre :
