This is also broken: Hilton Hotels login
Continuing on with the "Flash ads should never obscure content or functionality on a website" theme, today I noticed I couldn't log into my Hilton Hotel account because of some stupid ad for an olympics panda bear.
Here is me trying to login (click on the screenshot to see the .mov screen capture).
The sound you hear is me clicking and then smacking then punching my mouse button trying to get the login button to work. After I hit the teeny tiny close button, it works (the movie cuts off where my account page comes up immediately after).
