[Plugin: Google Maps v3 Shortcode] Balloon corners not showing

Hi there,

Great plugin but i`m having a couple of issues with the balloon not rendering properly on top right and bottom right,

I think it maybe either a css issue or javascript problem,

Here is the Dev site for you to view,

Any help with this would be greatly appreciated,

Regards,
