In the main webmail screen, say looking at inbox, you can click on a arrow icon to hide/unhide the advert that appears down the rightmost 25% or so of the screen, but as soon as you DO anything (like open an email or click on 'check mail' or the like) the advert once again encroaches on the screen.
This makes it beyond annoying (maybe Rogers should use that as their new marketing slogan).
