Page loading endlessly with embedded Google maps

On our blogs (e.g. http://Amsterdam.SpottedbyLocals.com) we
have a problem with the embedded Google maps links, which we enclose
in every post.

A posting with a Google map link, just keeps loading, and never stops loading… This results in other functions in the posting (like lightbox for images) not working.

Check for example this website
http://amsterdam.spottedbylocals.com/by-activity/bars-amsterdam/the-m…

I am sure this is only with posts with embedded Google map links in
them. If I take them out, everything’s fine….

Anybody know what could be wrong? Thanks a lot!
