GK Menu doesn't work in IE (7&8), no dropdown

Hello,

i noticed the GK menu doesn't work in IE (7&8)...the dropdown doesn't show.
My example url: http://caleidoscoop.rj8.nl/
It is the same on the Gavick template demo page (GK_boutique).

Does anyone know why? Is there a solution?

Thanks,
Ronald

having the same issue with Black & White template. The support sent me message stating that the problem comes from the validation errors on the codes. I just don't know where to edit the lines! Which file need to be edited to remove those errors? anybody has any idea?

btw, you can check your code here -> http://validator.w3.org/
