Flash Expanding Banner Tutorial Required

[Rik Comery]

Does anyone know how to create an expanding banner ad? The type where the banner is a set size, but on mouse over, it expands downwards, creating a larger advert, that overlaps the content of the HTML page.

I have seen this type of advert used on many sites, but am having problems finding anyone who knows how to do it.

If anyone can supply a link to a tutorial, or provide a working .fla file, that would be great.

I made some googling and find these;
Maybe can be helpful.

Also, I think these banners are annoying if you are using Firefox. Because as a bug it's always viewed expanded, when you see one in a site. It makes "browsing impossible" :).
