I have been a "supporter" if that is the right word of advertising on this site. Like it or not adverts are the lifeblood of this site providing as it does free advice and information.
But, I agree this advert which involves a large scroll down filling a large part of the page is beyond reason. As far as I can see it does not require any mouse over to make it work, simply opening a page on which it is active will trip it.
Has PCA sunk this low? I hope not.
