Itunes starts as black rectangle in Vista w Aero

Hi

Dell Inspiron 9200 w nvida geoforce go (latest drivers) 7900gs. When

iTunes starts it is just a black rectangle on the screnn. If I grab a

corner and resize it even slightly itunes looks fine. not a major

problem, but annoying. Anyone else have the same problem, or better yet

a fix?

Not looking to blame Dell, nvida, apple or MS, just looking to fix,

thanks
