Show direction map
it seem that Vantage having a minor bug in widget "show direction"
I figure out following (you could proof that in your demo sute aswell) at: http://demos.appthemes.com/?theme=vantage
in behalf of target (where and how you write it - the output manipulates the css !!!
in Chrome take a look at the target : Mexico city
and now target: Mexico
so I think it's appthemes task to clean.
