Problemer med Javascript rollover i IE 8

Hej
Jeg har problemer med Javascript og rollover i IE 8 (i firefox og  Chrome fungerer det fint).

Jeg har 4 links man kan køre musen henover hvorefter en række logoer skifter. Dette fungerer som sagt ikke, plus at et flash banner på selvsamme side stopper med at afspille.

Nogen idéer til hvad årsagen kan være?
