Pop ups generated by adverts

[BoneyBackJefferson]

I have a bulmers cider advert down the right hand side of the page and it seems to be generating a "one answer survey" pop up which when close generates another bulmers pop up.

This is on the AIBU main page.

Hi there,

That sounds odd! Any chance you could post a screenshot and let us know what you're using to browse the site?

I haven't had it since but will screen shot if it happens again, I am using IE 11 to browse the site.
