Take a look at this webpage.

careerbuilder jobsite navteq maps cannot close
It looks perfectly normal, and very functional until you put your mouse over that map. And all Hell break loose.

navteq maps blocking text, no way to close it
And then no matter what, that map won’t close.
I sent an email to ‘Contact Us’ at Navteq, it went like this:
“i’m at a job listing. i browse the description and accidentally hover my mouse over your maps. Your map enlarges itself on my page and covers some of the very important text i was reading. I look around for an ‘x’, clicked on all the buttons available on the maps and outside the maps itself, right-click, left-click, ctrl-click and nothing happens. Finally i give up and refreshes the page. i tiptoes my cursor around your map because i am not sure there is a way to close that thing. Or is there?”
I wonder what they’ll say.
