Hjælp til menu script

Jeg vil gerne have nedenstående script til at virke ens i både IE og NS. Når scripten indlæse i IE, er alle menupunkterne pænt lukkedet, men ikke i NS. I NS kan man trykke på punktet i menuen og ikke kun på gif, for at få undermenuen frem, det kan man ikke i IE.
Scriptet kan ses på www.kif-atletik.dk.

Spørgsmålet ligner et tilsvarende, så der er 30 bonus point at hente der. Håber på hurtigt svar.
