Yahoo! Canada Mail (Beta) - Where did the Advertisement go?

[prince_howie]

When I'm logged into Yahoo! Canada Mail (Beta), the advertisement at the right hand side of the screen is absent. Please note that I haven't clicked on the triangular token which is there to hide the advertisement. I am using Windows Vista, Premium Home Edition and Internet Explorer 7. If anyone has the answer please advise.

I just changed to the beta version and I don't see any ads on the right either.
Of course I don't want to see any. I have Adblock Plus and using Firefox, so
most ads are blocked anyway.
